Question

A waiter earned $23 in tips in an hour. He was paid in $1 bills and $5 bills. Use a model to determine how many $5 bills he received if he received a total of 15 bills.

Answer 1

We have a little system of equations here

let x represent the number of 1 dollar bills and 'y' represent the number of 5 dollar bills

we know they got 15 bills total so

x + y = 15

now we also know they earned 23 dollars total...so using the value of the money TIMES how much they got....we have

1x + 5y = 23


so how can we solve that system of equations?

x + y =15
1x + 5y = 23
