Answer:
7 ft 1 1/4 in
Step-by-step explanation:
The total width of 3 paintings and 2 spaces is ...
(10.5 in) + (3 in) + (3 ft 6 in) + (3 in) + (2 ft 2 3/4 in)
= (10.5 +3 +6 +3 +2.75) in + (3 +2) ft
= 25.25 in + 5 ft = 1.25 in + 24 in + 5 ft
= 7 ft 1 1/4 in
The total width of wall space needed for the paintings is 7 feet 1 1/4 inches.

Let the rate of commission is x%.
<u>Total earning is:</u>
- 7500 + 120000*x/100 = 13500
- 1200x = 13500 - 7500
- 1200x = 6000
- x = 6000/1200
- x = 5
