$18
$14
$10
$5

Answer 1

Answer:

$14

Solution:
Think of this as an algebraic equation, which would be expressed as 40+10s=total cost
The (s) would be the number of spinning classes you decide to take. Therefore to find the average cost of class, you would plug in 10 classes for s. This brings total cost to $140 dollars. To find the average you must divide this cost by the number of classes you took. This will be the price per each class, which is $14
