#### Answer

Cindy chose the number $5n+3$

#### Work Step by Step

Let us start at the number that Larry chose, $n$. First, we must multiply this number by $5$ because the problem states "5 times the number chosen by Larry", giving us $5n$. Then, we must add $3$ to this product, because the problem says that Cindy's number is $3$ more than the product we found. This gives us Cindy's number, which is $5n+3$
