Answer:
By 19% the computer was less than the original price
Step-by-step explanation:
The original price on the computer was $1500
Discount is 25%= 0.25
Discount amount = 1500 * 0.25 = 375
Discounted price = 1500 - 375 = 1125
Now 8% shipping cost to discounted price
8% = 0.08
Shipping cost = 1125 * 0.08 = 90
cost of computer with shipping cost = 1125 + 90 = 1215
Percentage less = (original cost - cost of computer now ) / original cost
= 
To get percentage we multiply by 100
0.19 * 100 = 19%
-- It takes 10 workers 3 days to build 1 house.
so
-- It takes 10 workers 1 day to build 1/3 of a house.
so
-- It takes 1 worker 1 day to build 1/30 of a house.
You got 15 workers and you need 4 houses ?
Well, as we just calculated . . .
-- It takes 1 worker 1 day to build 1/30 of a house.
so
-- It takes 15 workers 1 day to build 15/30 = 1/2 of a house.
so
-- It takes 15 workers 2 days to build 1 whole house.
so
-- It takes 15 workers 8 days to build 4 houses.
(a)
we can see that
curve is moving upward from t=0 to t=4
so, this is increasing interval.........Answer
(b)
we can see that
curve is moving upward from t=15 to t=18
so, this is increasing interval.........Answer
(c)
we can see that
curve is moving downward from t=4 to t=15
so, this is decreasing interval.........Answer
