Question

Lance had one-dollar bills. He went to the bank and exchanged the 4 one-dollar bills for 40 dimes. What is the relationship between the value of 1 dollar and the value of 1 dime?

Answer 1

We know that Lance has one-dollar bills, and that the the bank gave 40 dimes for 4 one-dollar bills

4 one dollar bills = 4 dollars in total

Since he received 40 dimes for the money he had

⇒ 4 dollars = 40 dimes

⇒ 1 dollar =
`(40)/(4)` dimes

⇒ 1 dollar = 10 dimes

Hence, this implies that 1 dollar is equal to 10 dimes
