A shop spends $2400 to purchase a batch of basketballs and footballs. There are 15 more basketballs than footballs. The selling price of a basketball is 20% higher than that a football. The selling price of each football is $60.A) Find the selling price of each basketball.
Selling price of a basketball = $60 x ( 1 + 20% ) = $60 x 120% = $72
B)
Let x be the number of footballs
Then there are (x+15) basketballs
60x + 72 (x+15) = 2400 + 660
132x +1080 = 3060
132x = 1980
x = 66
The shop has sold 66 footballs and 83 basketballs.

Let x be the number of basketball.
[60(1+20%)]x+60(x-15)=2400
Finish it by yourself.
[60(1+20%)]x+60(x-15)=2400
Finish it by yourself.
