Estimate the unit rate to the nearest whole number.

Question

$74.75 per 5 gallons. How much money per gallon?

Answer 1

To find the unit rate in dollars per gallon, we need to divide the total amount of money by the number of gallons.

We have:

• Total amount = $74.75
• Total gallons = 5 gallons

The unit rate (cost per gallon) can be calculated as follows:

\[ \text{Cost per gallon} = \frac{\text{Total amount}}{\text{Total gallons}} = \frac{74.75}{5} \]

Now, calculate the division:

\[ \frac{74.75}{5} = 14.95 \]

Now we round this to the nearest whole number:

\[ 14.95 \approx 15 \]

Therefore, the estimated unit rate is \(\boxed{15}\) dollars per gallon.

Answer 2

Estimate the unit rate to the nearest hundredth. $1.19 for every 12 oz. How much money per oz?

Answer 3

To find the unit rate in dollars per ounce, we need to divide the total amount of money by the number of ounces.

We have:

• Total amount = $1.19
• Total ounces = 12 oz

The unit rate (cost per ounce) can be calculated as follows:

\[ \text{Cost per ounce} = \frac{\text{Total amount}}{\text{Total ounces}} = \frac{1.19}{12} \]

Now, let's perform the division:

\[ \frac{1.19}{12} \approx 0.09916667 \]

Now, we round this to the nearest hundredth:

\[ 0.09916667 \approx 0.10 \]

Thus, the estimated unit rate is \(\boxed{0.10}\) dollars per ounce.
