Question 906391: At the local grocery store, apples are $1.20 per pound and oranges are $1.80 per pound. If the grocer wants to offer a 1.62-pound bag of mixed fruit for $1.62 per pound, how many pounds of apples must he use? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! a+b=1.62,
1.2*a+1.8*o=1.62*1.62
a=1.62-o
1.2*(1.62-o)+1.8*o=2.6244
1.944-1.2o+1.8*o=2.6244
0.6*o=0.6804
o=1.134
a=1.62-o
apple=0.486 lb. at $1.20
orange=1.134 lb. at $1.80
check
1.2*0.486+1.8*1.134=1.62*1.62
0.5832+2.0412=2.6244
2.6244=2.6244
ok
