Question

Music store marks up the instruments it sells by 30%.

If the store bought a guitar for $45, what will be its store price?
If the price tag on a trumpet says $104, how much did the store pay for it?
If the store paid $75 for a clarinet and sold it for $100, did the store mark up the price by 30%?

Answer 1

$58.50

$80

No

Explanation:

A: 30% of $45 means we must multiply 0.30 and 45. $45 x 0.30 = $13.50 is the markup. Next, add $13.50 to $45 for a total of $58.50 to get the total amount the store will charge with the markup.

B: X = price the STORE pays for instr.

130% X = $ 104

X = 104/(130%) = 104/1.3 = $ 80

No, It would have went up by 25% because 100%-25%=75%
