## Algebra 1: Common Core (15th Edition)

We use the word problem to set up the equation (Average=$\frac{aces} {numbergames}$ ) and fill our values accordingly.The average is 0.3 and the number of games is 70 so you have to find the number of aces. 0.3=$\frac{aces}{70}$ To solve this, you have to multiply both sides of the equation by 70 in order to isolate aces and solve the equation. 0.3$\times$70=ACES Aces=21
