Answer

### Estimate: 300 miles<br />### Exact: 314.19 miles

Explain

## Step1: Estimate the distance<br />### To estimate, we can round the values to make the calculation simpler. Round 155 miles to 150 miles and 7.4 gallons to 7.5 gallons. Then, calculate the miles per gallon and multiply by 15 gallons.<br />## Step2: Calculate the miles per gallon<br />### Calculate the exact miles per gallon by dividing the distance traveled by the gallons used: $\frac{155}{7.4}$.<br />## Step3: Calculate the exact distance for 15 gallons<br />### Multiply the miles per gallon by 15 gallons to find the exact distance Merryl's car can travel on a full tank.
