Answer:
<h3>Question 1</h3>
- Let number of adult tickets - x, student tickets - y
<u>Required equations:</u>
- x + y = 8
- 7.25x + 5.50y = 52.75
<u>Solve by substitution x = 8 - y</u>
- 7.25(8 - y) + 5.50y = 52.75
- 58 - 7.25y + 5.50y = 52.75
- 1.75y = 5.25
- y = 5.25/1.75
- y = 3
<u>Find x:</u>
Answer: 5 adults and 3 students
<h3>Question 2</h3>
- Pair of gloves costs- x, hats cost- y
<u>Equations:</u>
<u>Solve by elimination, subtract the equations:</u>
- 2y = 43 - 30
- 2y = 13
- y = 6.5
<u>Find x:</u>
- 2x = 30 - 13
- 2x = 17
- x = 8.5
Answer: Gloves cost $8.5, hats cost $6.5
Propecia:
5 gallons ====== $ 14.46.
16 gallons ======= x dollars
X=16*14.46: 5=46.27
Answer: $ 46.27.
