A 2018 Chevrolet Suburban averages 15 miles per gallon of gas in the city. It drives 47% farther per gallon of gas on the highway. If gas costs $3.25 per gallon, how much does a Suburban cost to drive per mile on the highway

On the highway, the cost to drive per mile is $2.21

Step-by-step explanation:

In the city the average distance per gallon is 15 miles

On the highway, he can drive 47% farther;

The distance he can cover on the highway per gallon will be;

15 + 47% of 15

= 15 + 0.47(15)

= 15 + 7.05 = 22.05

So on the highway, he can travel a distance of 22.05 miles

So the cost per mile on the highway would be;

$3.25 for 15 miles

$x for 22.05 miles

so we have the cost to drive per mile on the highway as;

(3.25 * 15)/22.05 = $2.21

answer: the correct answer is -32

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
