y = 80 - 2.75n

Step-by-step explanation:

Given

Beginning = 80

Rate = 2.75

Required

Model the situation using an equation

Represent the number of orders with n

Represent the balance with y

y is calculated as:

y = Beginning - Rate * n

We used minus because the amount is being deducted

y = 80 - 2.75* n

y = 80 - 2.75n
