Question (1):
Price last week = $6.00
Price this week = $7.20
Increased = $7.20 - $6.00 = $1.20
Answer : Percentage increased = $1.20/$6.00 x 100 = 20%
Question (2):
Original Price = $90
Marked down = 35% of $90 = 0.35 x 90 = $31.50
Price after marked down = $90 - $31.50 = $58.50
Answer: Lilly will pay $58.50 for the football cleats.
Answer:
<u>y = 3x + 8</u>
Step-by-step explanation:
line a: y = 3x + 11
This means that the slope is 3 and the y intercept is 11.
(-1,5)
line b: y = 3x + b <--- we need to solve for b and plug in the numbers from the coordinates
Just plug in the numbers!
5 = 3(-1) + b
5 = -3 + b
5 + 3 = b
8 = b
The y intercept is b! So the equation is:
y = 3x + 8
