Explanation

Find the number of CD players sold by Store S:

Table: 90 in stock
Graph: 80% sold
80% of 90 = 0.80 \times 90 = 72

Find the total cost of one CD player with sales tax:

Sales tax: 7% or 0.07
$119.95 \times 1.07 =$128.3465 (Since we are approximating, round to $128.35) If you forget how to compute sales tax, you can find the tax and add it to the item: 7% of$119.95 = 0.0.07 \times 119.95= 8.3965 (round to 8.4)

$119.95 + 8.4 =$128.35

Now find the cost of 72 CD players:

72 CD players \times $128.35 =$9241.20 The closest answer is \$9,240.

Hence option B is correct.
