Canada has a population that is about 1/10 as large as the united states. If canadas population is about 32 million, about how m
Mice21 [21]
Call Canada's population c, and call the U.S. population u.

We see that c=\frac{u}{10}.  Substituting 32 million for c, we see that 32,000,000=\frac{u}{10}.  Multiplying by ten, we see that 320,000,000=u.  By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.

Melinda and Marcus each have a job. Melinda earns $12 an hour. She also receives a $75 weekly bonus.
Olenka [21]
According to given information,
Equation of Melinda Earning = 75 + 12x
Equation of Marcus Earning = 15x
Where, x = Number of hours they worked.

Now, we need to calculate when they will have same amount of money, so for that instance they shall equal to each other.
75 + 12x = 15x
15x - 12x = 75
3x = 75
x = 75/3
x = 25

After 25 hours, they will have the money = 15(25) = $375

So, your final answer is $375

Hope this helps!
