Answer:
Step-by-step explanation:
Let x be the number.
Sum of five and 8 times a number: 8x + 5
Fifty plus one half of the number: 50 + (1/2)x

1/the rate of leakage per hour
This will give you the time it takes for 1 gallon to leak out in hours.
For example, if something is leaking at the rate of 12 gallons per hour, it will take 1/12 of an hour for 1 gallon to leak out. ( or 5 min)
Answer:
Function: C = 500 / n
Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.
Step-by-step explanation:
1. Cost per share, C, with respect to the number of contributors, n is
C = 500 / n
So, with 5 contributors, the price is $100 per share. $100 = 500/5
2. C= $20
20= 500 / n
20 * n = 500 * n
20n = 500
n= 25
She already has 5 contributors, so she needs 20 more.
