Answer 1

Elisa earns $400 per week plus $15 new customer
She made $400 one week plus $165 for 18 new customers

Answer 2

400+ (15c)

$670

Explanation:

Eliza earns per week = $400

She earns for each new customer's signs up = $15

Let the number of new customers Eliza signs up = c

The expression that shows her earning in a week will be

400+ (15c)

If the number of customers that signs up = 18

The weekly earning of Eliza will be = 400+(15 × 18)

= 400 + 270

= $670

Eliza's earning in a week would be $670.
