Question 382379
"2 hot dogs, 3 bags of potato chips, and 2 soft drinks for $5.50" ___ 2h + 3p + 2s = 550


"The price of a hot dog is $0.75 more than the price of a bag of potato chips" ___ h = p + 75 ___ h - 75 = p


"The cost of a soft drink is $1.75 less than the price of two hot dogs" ___ s = 2h - 175


you know the price of hot dogs relative to the other foods , so solve for h and use the result to find the others


substituting the equivalent values into the 1st equation ___ 2h + 3(h - 75) + 2(2h - 175) = 550


2h + 3h - 225 + 4h - 350 = 550 ___ 9h = 1125 ___ h = 125


(125) - 75 = p ___ 50 = p


s = 2(125 - 175) = 75
