A music store buys instruments and then sells them for 30% more than they paid
If the price tag on a trumpet says $104, how much did the store pay for it?


Sagot :

Answer:

Step-by-step explanation:

(104/x)+(30/100) cross multiply or

1040+3x

    10x

im not sure the answer but do like terms and you should get it!! im in a rush sorry if im no help <3

Let cost price=x
Then,x(1+30%)=104
x(1+0.30)=104
1.30x=104
1.30-:-1.30x=104-:-130/100
X=104*100-:-130
X=80



Therefore,cost price of trumpet for $80
