Answer:
=15
Step-by-step explanation:
1/2(24)+1/3(9)
=12+1/3(9)
=12+3
=15
Original price = $15
10% coupon = 10% x $15 = 0.10 x 15 = $1.50
Price after discount = $15 - $1.50 = $13.50
8% Tax = 8% x $15 = 0.08 x 15 = $1.20
Final Price = $15 - $1.50 + $1.20 = $14.70
Answer: $14.70

Answer:
The answer is y = -3x - 1.
Step-by-step explanation:
By converting into y = mx + b. You have to make y as the subject by substracting 3x to both sides:
3x + y = -1
3x + y - 3x = -1 - 3x
y = -3x - 1
