Question

I need help with this, please. Your family is driving from Harrisburg Pennsylvania to San Antonio, Texas a trip of 1430 miles. You begin the trip with a full tank of gas and after traveling 350 miles you refill the tank for $35. How much should you plan to spend on gasoline for the entire trip?

Answer 1

Estimate the total amount you should plan to spend on gasoline for the entire trip

Total distance of the trip = 1430 miles

After 350 miles, refill tank = $35

This means 350 miles cost $35

1430 miles cost $x

solve using ratio

350 : 35 = 1430 : x

350/35 = 1430 / x

10 = 1430/x

cross product

10x = 1430

Divide both sides by 10

x = 1430 / 10

x = $143

Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143
