Question

rosanne paid for an introduction to painting course at cool canvas art studio. the cost of the course covers 8 painting classes. she also bought a beginners painting kit for $42. rosanne paid $186 in all. which equation can you use to find the cost, c, of each painting class? 42(c + 8) = 186 42c + 8 = 186 8(c + 42) = 186 8c + 42 = 186

Explanation:

Step1: Define total cost components

Total cost = cost of 8 classes + cost of kit

Step2: Translate to equation

Let $c$ = cost per class. Cost of 8 classes is $8c$, kit cost is $42$, total is $186$.
$8c + 42 = 186$

Answer:

$8c + 42 = 186$
