Answer:
$8.25
Explanation:
discount = x
original price = $45.00
discount% = 15%
x/45 = 15/100
x · 100 = 15 · 45
100x = 675
100x/100 = 675/100
x = 6.75
Sale price = 15 - 6.75 = 8.25
Find the exact value using trigonometric identities. a MP3, 45, 0.15
so your answer is $45.15 that is how much it was before the discount :)
