Eric spent $60 on 5 shirts that each cost the same price. two of the shirts were blue .how much did the blue shirts cost?

DaniilM [7]

since they cost the same we can work out the price of one by dividing 60 by 5 which is 12

so if each one costs 12 and we need the price of 2 then we just do 12×2 which is 24

the answer is $24
