Question

Rafael rented a truck for one day. There was a base fee of 15.95, and there was an additional charge of 74 cents for each mile driven. Rafael had to pay 220.19 when he returned the truck. For how many miles did he drive the truck?

Answer 1

Answer is 276 miles driven

Step by step

We can use the y intercept formula for this
y = mx + b

We know y = $220.19
We know m = .74 (per mile)
We know b = $15.95 (base fee)

220.19 = .74x + 15.95

Solve

Subtract 15.95 from both sides to isolate variable

220.19 - 15.95 = .74x + 15.95 - 15.95

$204.24 = .74x

276 = x miles driven

Answer 2

Answer: He drove 276b miles with the truck

Step-by-step explanation: 220.19 - 15.95 = 204.24

204.24 / .74 = 276
