Answer:
8 Hours
Step-by-step explanation:
Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.
4 people x 14 hours = House
56 hours = House
56 hours is required to paint a house.
7 people x H hours= House
7 people x H hours = 56
(7 people x H hours)/ 7 = 56 / 7
You divide 7 on both sides to isolate H on one side.
H hours = 8
So H = 8 which is the amount of hours needed.

S = b + 15
s = skirt
b = blouse
The skirt is $15 more than the blouse
