Step-by-step explanation:

When you multiply exponents together, you simply add them.

-8 + 3 = -5.

The answer is c. Both plans will work for achieving the goal.

Step-by-step explanation:

 In the first case you must determine the amount of money you save per week in both plans, and then with that data calculate the amount of money saved in 6 or 8 weeks, depending on the case. For these calculations, you use simple rules of three, as will be shown below:

Plan A:

As previously mentioned, you will first calculate the amount of money saved in a week using a simple rule of three knowing that it works 9 hours per week: If in one hour you get $ 7.20, how much can you save in 9 hours?

money saved=$64.8 in 1 week

$ 64.8 is the money saved in a week.

So if that is the amount saved in 1 week, how much money will you save in 8 weeks?

money saved=$518.4 in 8 weeks

So, since $518.40 is bigger than $450, plan A will work.

Plan B:

Solving in the same way as in plan A, you can obtain:

If in one hour you get $ 6.50, how much can you save in 15 hours?

money saved=$97.5 in 1 week

$ 97.5 is the money saved in a week.

So if that is the amount saved in 1 week, how much money will you save in 6 weeks?

money saved=$585 in 6 weeks

Since $585.00 is bigger than $450, plan B will work, too.

Thus, both plans will work for achieving the goal.
