a taxi charges $2 per mile and $1 per person. If a ride for 2 people costs $12, how many miles was the ride?
Aliun [14]

Answer:

5 miles

Step-by-step explanation:

$12 = ($2 per mile) (2 people)

$12 = $2 + $2m (m = mile)

subtract 2 on both sides to eliminate

$12 - $2 = $2 - $2 + 2m

$10 = 2m

divide both sides by 2 to eleminate m

$10 / 2 = 2m / 2

m = 5

1 - 11 = -10 (to the left)
1 + 11 = 12 (to the right
