Question

A self-serve car wash charges $5.81 to use its facilities, plus an additional $0.51 for each minute the customer is at the self-serve car wash. If Tiffany was at the car wash for 5 minutes, how much was she charged?

Answer 1

Tiffany was charged $8.36

Explanation:

From the question, we can create the following equation where "c" is the amount of money she was charged, and "m" is the number of minutes Tiffany is in the car wash...

c = 0.51m + 5.81

Since in our case "m" equals 5, then...

c = 0.51m + 5.81

c = 0.51(5) + 5.81

c = 2.55 + 5.81

c = 8.36

Therefore Tiffany was charged $8.36

Answer 2

$31.06
$5.81 + the 51 cents equals to $6.32. $6.32 times 5 equals $31.06. Hope this helps!:)
