<span>Each hot dog costs $ 1.50 and each soda costs $ .50. You made a total of $ 78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs and soda's sold. How many hot dogs and soda's were sold?
Quantity Equation: h + s = 87 Value Equation:: 1.5h+0.5s=78.50
Multiply thru the Quantity Equation by 15 Multiply thru the Value Equation by 10.
15h + 15s = 15*87 15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520 </span>s = 52 (# of soda's sold) <span> Solve for h: h + s = 87 h + 52 = 87 h = 35 (# of hot dog's sold)</span>
