Question

paula buys 5 sandwiches. each sandwich is the same price. she has a coupon for $2 off the entire purchase. she pays a total of $50. which equation can be used to find the price, x, of one sandwich? $5x + 2 = 50$ $5(x - 2) = 50$ $5x - 2 = 50$ $5(x + 2) = 50$

Explanation:

Step1: Define total pre-coupon cost

Let $x$ = price of 1 sandwich. Total for 5 sandwiches: $5x$

Step2: Apply $2 coupon discount

Subtract coupon from total: $5x - 2$

Step3: Set equal to final payment

Final paid amount is $50: $5x - 2 = 50$

Answer:

$\boldsymbol{5x - 2 = 50}$
