Question

what is the answer for 2 1/4 lb of ground beef and 1 3/4 lb of ground pork. The ground pork costs $1.20 more per pound than the ground beef. The total cost for the meat was $15.22.

Answer 1

b+1.20=p
2.25b+1.75p=15.22

sub b+1.20 for p
2.25b+1.75(b+1.20)=15.22
2.25b+1.75b+2.1=15.22
minus 2.1 from both sides
4b=13.12
divide both sides by 4
b=3.28

sub back

b+1.20=p
3.28+1.20=p
4.48=p




2.25*3.28=7.38
1.75*4.48=7.84
