olga_2 [115]

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

<em>Total distance of the trip</em> = 1430 miles

<em>After 350 miles, refill tank</em> = $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

<em>cross product</em>

10x = 1430

<em>Divide both sides by 10</em>

x = 1430 / 10

x = $143

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