Answer: 4

----------------------------------------------------------------------------------------------
Information Given
----------------------------------------------------------------------------------------------
Entree = $4.75
Addition items = $1.25 each

----------------------------------------------------------------------------------------------
Define x
----------------------------------------------------------------------------------------------
Let the number of addition item be x

----------------------------------------------------------------------------------------------
Construct equation
----------------------------------------------------------------------------------------------
9.75 = 4.75 + 1.25x

----------------------------------------------------------------------------------------------
Find x
----------------------------------------------------------------------------------------------
9.75 = 4.75 + 1.25x

----------------------------------------------------------------------------------------------
Subtract 4.75 from both sides
----------------------------------------------------------------------------------------------
5 = 1.25x

----------------------------------------------------------------------------------------------
Divide by 1.25 on both sides
----------------------------------------------------------------------------------------------
4 = x

----------------------------------------------------------------------------------------------
Answer: The customer ordered  4 additional items

Hello!

ANSWER:

4 additional items were ordered.

EXPLANATION:

First, subtract the cost of the entree:

9.75 - 4.75 = 5

This means that the customer spent $5.00 on on additional items.
Each additional item costs $1.25. Divide:

5 ÷ 1.25 = 4
