A soccer ball costs 1.5 times the amount of a volleyball. If one of each is purchased and the total price is $37.70 before tax, what's the price for each ball?
Soccer is volleyball + 1.5. Replace soccer ball in the equation soccer + volleyball = 37.70 with v + 1.5. Now you have 1.5+v+v=37.70. Combine like terms to get 2v+1.5=37.70. Subtract 1.5 and divide by two. Then insert v to find s. V=volleyball S=soccer ball
