Answer:  25

<u>Step-by-step explanation:</u>

   7(x - y) - 3(2 + 2x)

= 7x - 7y  - 6  - 6x

=   x - 7y  - 6

for x = 3, y = -4

      3 - 7(-4) - 6

=     3 + 28  - 6

=         31     - 6

=             25

Blizzard [7]

Answer:

Cost of purchase and installation = 5323.50

Cost per window = 230.25

Cost of installation = 2100

5323.50 - 2100 = 3,223.50

Therefore, the number of windows purchased is :

(Total purchase cost of windows alone / price per window)

(3,223.50 / 230.25)

= 14

Hence, 14 windows was purchased
