Question
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?
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
