This question has two parts. First, answer Part A. Then, answer Part B.
Part A
Salim has 9 five-dollar bills and ten-dollar bills in his wallet. The total amount in his wallet is $60. This situation can be represented with the system x+y=9
and 5x+10y=60
, where x
represents the number of five-dollar bills and y
represents the number of ten-dollar bills. Solve the system of equations by graphing. Graph both equations on the coordinate plane even if they represent the same line.
