Answer:
30%
Step-by-step explanation:
This is how I would solve it: First you have to find 1 percent of $450. So:
450/100 = 4.5
Now, we have to find the difference between $450 & $315, which is $135. Now, we have to divide $135 by 4.5, which equals 30. So, the markdown is 30%. Basically:
450/100 = 4.5
450 - 315 = 135
135/4.5 = %30
The markdown is 30%.
y = 4x + 1
check
for x = 1 → y = 4(1) + 1 = 4 + 1 = 5 OK
for x = 4 → y = 4(4) + 1 = 16 + 1 = 17 OK
for x = 5 → y = 4(5) + 1 = 20 + 1 = 21 OK
for x = 7 → y = 4(7) + 1 = 28 + 1 = 29 OK
for x = 9 → y= 4(9) + 1 = 36 + 1 = 37 OK
