Since x and y must be positive, 7x and 11y are positive either. That means 7x + 11y > 0. Then we would obtain N > 0 because 7x + 11y = N. That also means N must be positive. So if we set N to be zero or negative, there would be no solution. Thus, to produce an answer of No solution, the highest number N could be is 0.
Answer:
1. The domain for the number of fruit cups is 0 minimum and 20 maximum.
[0 < x < 20].
2. [10 < y < 70]
Step-by-step explanation:
1. The domain is 0 to 20 because there are 20 people total who will each have a fruit cup
2. The range is $10 to $70 because the minimum price is $10 without any fruit cups and $70 when there are 20 fruit cups.
The candle would burn for 18 hours.
45 / 15 = 3
If the candle is three times longer than normal, it will burn three times longer than normal.
3 x 6 = 18
X= 10 I did it on my calculator so don’t worry :)
