To solve the equation \(-2x + 902 = 1,518\), we can follow these steps:
1. Subtract 902 from both sides:
\[
-2x = 1,518 - 902
\]
2. Calculate the right side:
\[
1,518 - 902 = 616
\]
So, we now have:
\[
-2x = 616
\]
3. Divide both sides by -2 to solve for \(x\):
\[
x = \frac{616}{-2} = -308
\]
Now let's evaluate the responses given:
1. 300
2. -600
3. -300
4. 600
The closest estimate for \(x = -308\) among the responses is \(-300\).
Therefore, the best estimate for \(x\) is \(\text{−300}\).
1. Subtract 902 from both sides:
\[
-2x = 1,518 - 902
\]
2. Calculate the right side:
\[
1,518 - 902 = 616
\]
So, we now have:
\[
-2x = 616

\[
x = \frac{616}{-2} = -308

To find the total number of cells in the three petri dishes, we can add the number of cells in each dish together:
- First dish: 22,340 cells
- Second dish: 43,560 cells
- Third dish: 36,612 cells
Now, let's calculate the total:
\[
22,340 + 43,560 + 36,612 = 102,512
\]
Now, we can find the closest estimate among the provided responses:
1. 10,000
2. 100,000
3. 1,000,000
4. 150,000
The total number of cells, which is approximately 102,512, is closest to **100,000**.
Therefore, the best response is **100,000**.
- First dish: 22,340 cells
- Second dish: 43,560 cells
- Third dish: 36,612 cells
Now, let's calculate the total:
\[
22,340 + 43,560 + 36,612 = 102,512
\]
Now, we can find the closest estimate among the provided responses:
1. 10,000
2. 100,000
3. 1,000,000
4. 150,000
The total number of cells, which is approximately 102,512, is closest to **100,000**.
Therefore, the best response is **100,000**.

To solve the equation
\[
\frac{x}{50} - 94 = 189,
\]
we can follow these steps:
1. Add 94 to both sides of the equation:
\[
\frac{x}{50} = 189 + 94
\]
2. Calculate the right side:
\[
189 + 94 = 283.
\]
Now we have:
\[
\frac{x}{50} = 283.
\]
3. Multiply both sides by 50 to solve for \(x\):
\[
x = 283 \times 50.
\]
4. Calculate \(283 \times 50\):
\[
x = 14,150.
\]
Now, let's evaluate the responses given:
1. 150,000
2. 15,000
3. 150
4. 1,500
The closest estimate for \(x = 14,150\) among the responses is **15,000**.
Therefore, the best estimate for \(x\) is **15,000**.
\[
\frac{x}{50} - 94 = 189,
\]
we can follow these steps:
1. Add 94 to both sides of the equation:
\[
\frac{x}{50} = 189 + 94
\]
2. Calculate the right side:
\[
189 + 94 = 283.

Now we have:
\[
\frac{x}{50} = 283.

First, let's calculate the total number of tacos sold:
- Carne asada tacos: 11,321
- Chicken tacos: 13,132
- Carnitas tacos: 8,982
Now, add these numbers together:
\[
11,321 + 13,132 + 8,982 = 33,435
\]
Next, to estimate the total earnings from tacos, we will multiply the total number of tacos by the price per taco ($3.89):
\[
\text{Total earnings} = 33,435 \times 3.89
\]
To make the multiplication simpler, we can round the price of each taco to $4.00 for estimation:
\[
\text{Estimated earnings} \approx 33,435 \times 4 = 133,740
\]
Now, let's evaluate the provided responses:
1. **$130,000**
2. **$33,000**
3. **$160,000**
4. **$90,000**
The best estimate for total earnings is **$130,000**.
- Carne asada tacos: 11,321
- Chicken tacos: 13,132
- Carnitas tacos: 8,982
Now, add these numbers together:
\[
11,321 + 13,132 + 8,982 = 33,435
\]
Next, to estimate the total earnings from tacos, we will multiply the total number of tacos by the price per taco ($3.89):

To solve the equation
\[
21x + 1,998 = 2,243,
\]
we can follow these steps:
1. Subtract 1,998 from both sides:
\[
21x = 2,243 - 1,998.
\]
2. Calculate the right side:
\[
2,243 - 1,998 = 245.
\]
So now we have:
\[
21x = 245.
\]
3. Divide both sides by 21 to solve for \(x\):
\[
x = \frac{245}{21}.
\]
4. Now, performing the division:
\[
x = 11.6667.
\]
Since we are looking for an estimate, we can round this to approximately 12.
Now, let's examine the response choices provided:
1. 1,000
2. 10

The closest estimate to \(x \approx 12\) among the responses is **10**.
Therefore, the best estimate for \(x\) is **10**.
\[

we can follow these steps:
1. Subtract 1,998 from both sides:
\[
21x = 2,243 - 1,998.
\]
2. Calculate the right side:
\[
2,243 - 1,998 = 245.
