Meryl spent a total of $68.82 for two pairs of sneakers with the same cost the sales tax is $5.32 meryl also uses a coupon for three dollars off a purchase how much does each pair of sneakers cost

each pair of sneakers cost $33.25

Step-by-step explanation:

Let x represent the cost of one sneaker. The two pairs of sneakers cost the same. Therefore, the cost of two sneakers would be 2x.

The sales tax is $5.32. This means that the cost of the two pairs of sneakers would be 2x + 5.32. Meryl also uses a coupon for three dollars off a purchase. This means that the final cost of the two pairs of sneakers would become

2x + 5.32 - 3 = 2x + 2.32

Meryl spent a total of $68.82 for two pairs of sneakers. Therefore,

2x + 2.32 = 68.82

2x = 68.82 - 2.32 = 66.5

x = 66.5/2 = $33.25

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
