[tex]\bold{y=400 + 15c}[/tex] is the expression that shows how much Eliza earns in a week
Solution:
Given the amount Eliza earns per week (initial amount) = [tex]\$400[/tex]
The amount for each new customer (additional amount)= [tex]\$15[/tex]
The number of new customers = c
[tex]\bold{\text { Total amount }=\text { Initial amount + (Number of new customers) } \times \text { (amount per each customer) }}[/tex]
Assuming the total amount as y we get,
[tex]\text { y }=\$ 400+c \times \$ 15[/tex]
The required equation is [tex]\text { y }=400+15c[/tex]
