Using some identities for solution
I hope that it's a clear solution.
The number of months when the gyms cost the same is 5 months.
<h3>When would the cost be the same?</h3>
Total cost of joining the gym = registration fee + (cost per month x number of months)
- Hunkey Heros = $50 + $20m
- Zipity-zapity- zap-that-fat = $70 + $10m
When the gyms costs are the same, the two above equations would be equal to each other:
50 + 20m = 70 + 10m
20m - 10m = 70 - 20
10m = 50
m = 50 / 10
m = 5

Answer:
B
Step-by-step explanation:
R = recycling and reuse industry jobs
w = waste management jobs
we know, those two jobs combined are 1,275,000
or
r + w = 1,275,000
we also know that, whatever the "w" jobs are, are really less than "r"
jobs by 1,025,000
"r" has 1,025,000 more than "w"
or
r = w + 1,025,000
or
r-w = 1,025,000
so... there, just solve by elimination, simple, notice the "w",
is just waiting to be eliminated :)
