Answer 1

Given that Jeannette has $5 and $10 bills in her wallet.

Let t represent the number of tens.

The number of fives is eight more than five times the number of tens. It can be written as follows.

`\text{five times the number of ten=5 times t=5t}`
`\text{more than 8 means add 8 }`

`\text{8 more than five times the number of ten=5 times t+8=5t}+8`
`\text{The number of fives =5t+8}`

Hence the expression for the number of fives is

`5t+8`
