Answer by Maths68(1474) (Show Source): You can put this solution on YOUR website!
Number of Kind 1 mangoes = m
Number of Kind 2 mangoes = 90-m
Cost of Kind 1 mango = 10.00
Cost of kind 2 mango = 12.50
Number of mangoes in Mixture = 90
Cost of mango in Mixture = 11.75
(m)(10)+(90-m)(12.5)=11.75*90
10m+1125-12.5m=1057.5
10m-12.5m=1057.5-1125
-2.5m=-67.5
-2.5m/-2.5m=-67.5/-2.5
m=27
Number of Kind 1 mangoes = m=27
Number of Kind 2 mangoes = 90-m=90-27=63
