4) Answer the question.

Solution

four ipads and three laptops for the school library for a total cost of 855.00.

three more ipads and five more laptos for 1150.00.

Let price of each ipad be ---x

Let price of each alptops be --->y

Equation 1: 4x +3y = 855

Equation 2: 3x +5y = 1150

To solve the equation: use elemination method-

4x +3y = 855 x 3

3x +5y = 1150 x 4

---------------------------

x = $ 75 and y = $ 85
