Let " h " be the price of hamburgers per pound, and
let " s " be the price of sugar per pound.
Then from the condition you have these two equations in 2 unknowns
4h + 3s = 230 cents (1)
2h - 5s = 50 cents (2)
Multiply equation (2) by 2 (both sides) and then subtract it from equation (1). You will get
13s = 230 - 2*50 = 130;
hence, s = 130/13 = 10.
Thus one pound of sugar costs 10 cents, or $0.1.
Then from equation (2), h =
=
=
= 50 cents.
ANSWER. The price for hamburgers is 50 cents per pound; for sugar 10 cents per pound.
