Question

One envelope contains only $5 bills, another envelope contains only$10 bills, another envelope contains only $20 bills, and the last envelope contains only$50 bills. No envelopes are empty and each of the four contains the same number of bills. All of the bills are exchanged for $100 bills (the total dollar amount remains same). Find the least possible total number of bills in all four envelopes. Answers 1. thuthao Answer: The least possible number is 20 bills in each envelope, which means 80 total bills. With a total of$1700
Step-by-step explanation:
Okay so what they are asking is the least number of bills in each of the envelopes, WHILE the total can be exchanged for $100 only and all the envelopes have the exact same amount of bills. 5 + 10 + 20 + 50 =$85
(adding these totals because they told us to have equal amounts of bills in each envelope)
85 x n = (number divisible by 100)
n = number of bills
first least number possible was 20
85 x 20 = 1700
