17. Mr. Morro fills his gas tank with 6 gallons of gas that costs \( \$ 26.58 \). At this rate, how much will it cost to purchase 13 gallons of gas? Show or explain how you got your answer.

To find out how much it will cost to purchase 13 gallons of gas, we first need to determine the price per gallon. Mr. Morro paid \$26.58 for 6 gallons, so we calculate the price per gallon by dividing the total cost by the number of gallons: \[ \text{Price per gallon} = \frac{\$26.58}{6 \text{ gallons}} \approx \$4.43 \text{ per gallon} \] Next, we multiply the price per gallon by the number of gallons (13) to find the total cost: \[ \text{Total cost for 13 gallons} = 13 \text{ gallons} \times \$4.43 \text{ per gallon} \approx \$57.59 \] So, it will cost approximately \$57.59 to purchase 13 gallons of gas.
