• A.

11

• B.

-22

• C.

0

• D.

-11

• E.

Not above

B. -22
Explanation
The expression (-11) - (11) can be simplified by subtracting 11 from -11. When subtracting a positive number from a negative number, we add the absolute values and keep the sign of the larger number. In this case, the absolute value of -11 is 11, and the absolute value of 11 is also 11. Therefore, adding 11 and 11 gives us 22, and since the larger number is negative, the result is -22.

### Julie's parents give her a weekly allowance. She spent \$2 at the movies, \$6 at the Mall, \$14 at the zoo, over the week, and \$8 for lunch every day. How much money do they give her weekly?

• A.

\$10

• B.

\$40

• C.

\$78

• D.

\$20

C. \$78
Explanation
To determine how much money Julie's parents give her weekly, we can calculate her weekly expenses and then subtract those expenses from her weekly allowance.

Weekly Expenses:
- \$2 at the movies
- \$6 at the mall
- \$14 at the zoo
- \$8 for lunch every day (7 days a week)

Now, let's calculate the total weekly expenses:

Weekly Expenses = \$2 (movies) + \$6 (mall) + \$14 (zoo) + \$8 per day for lunch x 7 days = \$2 + \$6 + \$14 + \$56 = \$78

To find Julie's weekly allowance, we need to add the weekly expenses to her total weekly spending:

Total Weekly Spending = Total Weekly Expenses

Weekly Allowance = Total Weekly Spending

So, Julie's parents give her a weekly allowance of \$78.

• D.

A. Ken
Explanation
Ken makes more money in a week compared to Carl because he works more hours. Ken works 8 hours a week and makes \$6 an hour, so his total earnings per week would be 8 x \$6 = \$48. On the other hand, Carl works 4 hours a week and makes \$8 an hour, so his total earnings per week would be 4 x \$8 = \$32. Therefore, Ken makes more money in a week than Carl.
