C(s) = 175s + 4500 or y = 175x + 4500
cost of 12 tons of sugar...
C(12) = 175(12) + 4500
C(12) = 2100 + 4500
C(12) = 6600....so 12 tons of sugar will cost u $ 6600
4:10 is the time that the class ends, I think that's what you meant?
Answer:
Step-by-step explanation:
<u>Given</u>
- Daily charge = $68.80
- Charge per mile = $0.08
- Target distance = 325 miles
- Money limit = $370
<u>Required inequality:</u>
<u>Solving for d:</u>
- 68.8d + 26 ≤ 370
- 68.8d ≤ 344
- d ≤ 344/68.8
- d ≤ 5
Up to 5 days is the answer
Given
MINING A mine produces 42.5 tons of coal per hour.
Find out the how much coal will the mine produce in 9.5 hours.
To proof
As given in the question
A mine produces 42.5 tons of coal per hour i.e in the 1 hour mine produces the 42.5 tons .
Let us assume that the coal produce in the 9.5 hours be x.
than the equation becomes
x = 9.5 × 42.5
x = 403 . 75 tons
403 . 75 tons coal will the mine produces in the 9.5 hours.
Hence proved
