Question

Wendy earns $2 for every table she serves plus 20% of the total customer order. How do you define a variable and write an expression to represent the amount of money she earns for one table?

Answer 1

`$t=$2+20/100$v`

See explanation

Explanation:

Let total income per table be `$t`
Let the value of the order for 1 table be `$v`

Note that % is a unit of measurement and it is worth `1/100`
so 20% is the same as `20/100`

`$t=$2+20/100$v`
