Question

a bank teller cashed a check for $200 using $5 bills then than $10 bills. The bank teller handed 25 more $5 bills than $10 to bills to the customer. Determine how many bills of each domination were handed to the customer.

Answer 1

f = # of five dollar bills
t = # of ten dollar bills

f = t + 25
5f + 10t = 200

substitute what f = into the second equation.

5(t + 25) + 10t = 200
5t + 125 + 10t = 200
15t + 125 = 200
15t = 75
t = 5
f = t + 25 so f = 5 + 25 so f = 30

5 ten dollar bills
30 five dollar bills
