Write and solve a system of equations that represents each situation. Interpret the solution. Neil has a total of twelve $5 and $10 bills in his wallet. He has 5 times as many $10 bills as $5 dollar bills. How many of each does he have?
Answers
x - $5 bills y - $10 bills
x + y = 12 y = 5x
x + (5x) = 12 6x = 12 x = 2
y = 5(2) y = 10
10 $10 bills and 2 $5 bills
Let $5 bills be denoted by x and $10 bills be denoted by y.
