The boys will pay $2100 all together
Step-by-step explanation:
Given
Total boys = 60
Cost of Shorts = $20
Cost of Shirt = $15
As each boy has to buy a shorts and a shirt, so there will be 60 shirts and 60 shorts bought.
Multiplying the cost of one shorts with number of boys will give us the total price of shorts for 60 boys
Cost of shorts for 60 boys = [tex]20*60 = 1200\ dollars\\[/tex]
Multiplying the cost of one shirt with the number of boys will give us the total cost for 60 shirts
Cost of shirts for 60 boys = [tex]15*60 = 900\ dollars[/tex]
So,
[tex]Total\ cost\ paid\ by\ boys = Cost\ of\ shirts + Cost\ of\ shorts\\= 900+1200\\=2100[/tex]
Hence,
The boys will pay $2100 all together
