Question

Ben rents a car for one day. The charge is $20 plus the $0.12 per mile. He wants to spend exactly $80. How many miles can he drive? Write and solve an equation to find how many miles Ben can driv

Answer 1

Ben can drive 500 miles for $ 80

Explanation:

Let y be the cost of traveling and x be the number of miles . The charge is $20 plus the $0.12 per mile which means the cost $ 20 is constant and an additional cost of $ 0.12 is spent on every mile. Then according to the given conditions the equation will be

y = $20 + $ 0.12(x) where x is the number of miles

Now we can solve x for y= 80

$ 80= $20 + 0.12 (x)

$ 60 = 0.12x

x= 60/ 0.12= 500

Ben can drive 500 miles for $ 80
