Question

The junior class is selling donuts for a fundraiser. The students are selling the donuts by the dozen. If they want to sell one dozen for $12, write an inequality to find how many dozen donuts they need to sell to make at least $1,000 and find the solution?(1 point)

Answer 1

To find the number of dozen donuts the junior class needs to sell to make at least $1,000, we can set up the following inequality:

Let \( d \) represent the number of dozens sold.

The revenue from selling \( d \) dozens of donuts at $12 per dozen can be represented as:

\[
12d \geq 1000
\]

Now, we can solve for \( d \):

1. Divide both sides of the inequality by 12:

\[
d \geq \frac{1000}{12}
\]

2. Calculate \( \frac{1000}{12} \):

\[
\frac{1000}{12} \approx 83.33
\]

Since \( d \) must be a whole number (you can't sell a fraction of a dozen), you would need to round up to the next whole number.

Thus, the solution is:

\[
d \geq 84
\]

The correct response is:

**12d ≥ 1000 and 84**
