Question

Marty made a $220 bank deposit using $10 bills and $5 bills. She gave the teller a total of 38 bills, how many $5 bills were in the deposit?

Answer 1

Answer:

Step-by-step explanation: Let x = number of $5 bills

Let y = number of $10 bills

Use these variables to set up equations to represent total deposit and number of bills.

x + y = 38 eq1 ----> total number of bills

5x + 10y = 220 eq2 -----> total deposit
