i need some help with this problem A freight truck must drive a load 1,450 miles. If the truck gets 9 miles to the gallon and diesel fuel costs $4.25 per gallon, how much money will the truck driver spend on fuel during the trip?

Respuesta :

First we need to find how many gallons are used

d = m * g where m is miles per gallon and g is number of gallons

1450 miles = 9 miles per gallon * g

Divide each side by 9

1450/9 = g

161 1/9 gallons

( 161.111111 repeating)

Now multiply by the price per gallon

161.11111111 gallons * 4.25 dollars per gallon

684.7222222222 dollars

Rounding to the nearest cent

$684.72
