A music store marks up the instruments it sells by 30%
a, if the store bought a guitar for $45, what will be its store price
b. If the price tag on a trumpet say $104, how much did the store pay for it?

Respuesta :

Answer:

A. $58.50, B. $80

Step-by-step explanation:

mark up percentage [tex]\frac{store price - actual price}{actual price}[/tex] x 100

30 x 45 = 100SP - 4500

5850 = 100SP

Store Price > therefore, $ 58.50

A. $58.50

Actual Price :

130 AP = 10400 - 100AP

AP > $80

B. $80
