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.
[tex]\text{five times the number of ten=5 times t=5t}[/tex][tex]\text{more than 8 means add 8 }[/tex][tex]\text{8 more than five times the number of ten=5 times t+8=5t}+8[/tex][tex]\text{The number of fives =5t+8}[/tex]Hence the expression for the number of fives is
[tex]5t+8[/tex]
