Answer:
p(x) = 7/5 x + 5.
Step-by-step explanation:
The slope of the function = difference in values / f(x) / difference in values of x
= (19-12) / (10 - 5) = 7/5
also:
(26-19) / ( 15 - 10) = 7/5
and (33-26) / (20-15) = 7/5.

Answer:
$168.75
Step-by-step explanation:
if it's narked down by 20% then $135 is 80% of the original price
80 = 135
100 = x
80x = 100×135
x = $168.75
A bike is on sale for $135. The original price of bike is 135
