Answer:
$33.92
Step-by-step explanation:
First, we have to find how much the sale price for the tennis racket is before tax.
100% - 20% = 80% Marcus has to pay 80% of the original price.
80% * 40 = .8 * 40 = 32
Marcus has to pay $32 for the tennis racket before tax.
6% = .06 (tax percentage)
.06 * 32 = 1.92 ————> tax
Add the tax with the sale price.
32 + 1.92 = 33.92
Marcus has to pay $33.92 for the tennis racket.

Answer:
x= 12.528
*rounded is 12.53 or 12.5
Step-by-step explanation:
7.3 ^2 + x^2 = 14.5^2
53.29 + x^2 = 210.25
-53.29 -53.29
x^2= 156.96
x= 12.528
Your expected value is -$0.62.
We multiply the probability of winning by the amount won. There are 12 face cards out of 52 cards, and the amount won is 4:
12/52(4)
We also multiply the probability of losing by the amount lost. There are 40 cards that are not face cards out of 52, and the amount lost is 2:
40(52)(-2)
Adding these, we have:
(12/52)(4)-(40/52)(2) = -0.62.
