carla paid for an introduction to painting course at color castle art studio. the cost of the course covers 12 painting classes. she also bought a beginners painting kit for $28. carla paid $220 in all. how much does each painting class cost?

Answer

Explanation:

Step1: Subtract kit cost from total

Let $x$ be the total cost of 12 - class course. We know that the total amount paid is $220$ and the cost of the painting - kit is $28$. So, $x=220 - 28$. $x = 220-28=192$

Step2: Calculate cost per class

If the total cost of 12 classes is $x = 192$, and we want to find the cost per class $y$. We use the formula $y=\frac{x}{12}$. $y=\frac{192}{12}=16$

Answer:

$16$
