Question

linda wants to buy 2 sweaters and a pair of sunglasses at wild orchids. each sweater costs the same amount. the sunglasses cost $12. which equation can be used to find the total cost of her purchases? 12s - 2 = c; 12s + 2 = c; 2s - 12 = c; 2s + 12 = c

Explanation:

Step1: Define variables

Let $s$ = cost of 1 sweater, $C$ = total cost

Step2: Calculate sweater total cost

Total for sweaters: $2 \times s = 2s$

Step3: Add sunglasses cost

Total cost = sweater cost + sunglasses cost: $2s + 12 = C$

Answer:

$2s + 12 = C$
