You would take the beginning number and subtract the second number then you would take the number you got and divide it by the first number.

1420-1022=y then y/1420

Is this right? i’m not sure

My only issue is that it says numbers between. It does not say including. Therefore, I think you want to use > and < instead of the ones with equals signs attached.

Sally works 40 hours a week and makes $30 an hour, but her kids are in child care each day and the day care center charges her $
Lapatulllka [165]

Answer:

Sally will earn $21.25 per hour after she removes day care charges from her total earnings.

Step-by-step explanation:

Hey there!

Let's start by solving for how much money that Sally earns per week.

To find this value, we will find the product of 40 hours per week and 30 dollars per hour.

40\times30=1200

We now know that Sally makes $1,200 a week without deducting the daycare charges per day.

However, we know we need to deduct 70 dollars for each day that Sally works. Since she works for five days a week, we will find the product of 70 dollars per week and five days a week.

70\times5=350

Therefore, the day care charges $350 per week.

Finally, we need to subtract the day care charges from the amount of money that Sally earns to find how much she actually makes in a week.

1200-350=850

Therefore, for forty hours of work that Sally works each week, she earns $850.

However, we are not done. The question asks us to find how many dollars <u>per hour</u> does she actually make? Therefore, we need to find the quotient of 850 dollars and 40 hours per week.

\displaystyle \frac{850}{40}=21.25

Therefore, Sally earns $21.25 each hour after deducting day care costs.

Lera25 [3.4K]
A prime number is a number whose factors are 1 and itself
Eg 7
7 is a prime number because it only comes in table one and 7
Or it’s only factors are 1 and itself
A composite number comes in 1, itself and other tables
Eg. 16
It comes in table 1, 2, 4 and 16
