You are going to the movie theater with your parents and your 8 year-old brother. Adult tickets cost $8, ages 10 -18 cost $7.25 and under age 10 cost $4.25. If you spent an additional $20 on soda and popcorn, what is the total cost of your trip to the movie theater

Answers

total cost = 47.25 if your age is between 10 - 18

Answer:

The answer is $47.50

Step-by-step explanation:

All you have to do is add up the price of each person attending with what age price for each and then add the additional $20 for the sodas and popcorn.

Two parents = 8.00 + 8.00 = $16.00

"You" would most likely be student price, so.. = $7.25

And 8 year-old little brother is under 10, so.. = $4.25

Adding up those three prices we get $27.50, now all to do is add the additional drinks and snacks price. 27.50 + 20.00 = $47.50

Two angles are supplementary. The first angle measures 60°. What is the measurement of the second angle? A. 90°
B. 30°
C. 120°
D. 180°

Answers

Supplementary angles are two angles that have a sum of 180°. 

If the first angle measures 60°, then the second angle is 120°.

180° - 60° = 120°  Choice C.

The measurement of the second angle is 120°.

Hence, the correct answer is C. 120°.

Here, we have,

Two angles are considered supplementary if their sum is equal to 180°.

In this case, we are given that the first angle measures 60°.

To find the measurement of the second angle, we subtract the measurement of the first angle from 180°:

180° - 60° = 120°

Therefore, the measurement of the second angle is 120°.

Hence, the correct answer is C. 120°.
