Answer: 6%
Step-by-step explanation:
Let's assume that this function is linear.
Take any 2 of the points and find the slope of the line segment connecting them:
103 - 80
m = ------------- = 23, meaning $23 per day. Subtracting $23 from $34 (in the table), we get $11. Thus, the correct linear relationship is B.
4 - 3
Answer:
$12, 14%
Step-by-step explanation:
Find the amount of discount:
84 - 72 = 12
Find the amount of discount as a percentage
12 / 84 = 0.1428
