Billy and 3 of his friends want to take a road trip, but have a limited
amount of money. billy's car holds 4 people and gets 34 miles per
gallon of gas (mpg). the students want to go to san francisco for the
day. it is 646 miles (round-trip) to san francisco, and gas is $2.00
per gallon. how much money would each student have to pay in order
for them to make it to san francisco and back home again?

$9.50

Step-by-step explanation:

to drive 646 miles with 34 miles per gallon, the amount of gallons of gas needed will be:

646/34 = 19 gallons of gas

$2 is the cost of 1 gallon, so 19 gallons would cost:

19 * 2 = $38

Billy and 3 friends = 4 person

Each would pay:

38/4 = $9.50 per person

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

yes
