Frieda sells caps at a market. If she charges R50 per cap she sells 26 caps per day. If she
charges R80 per cap she sells only 11 caps per day. Let x represent the price of a cap and let
y represent the number of caps that is sold per day. If the number of caps sold is dependent
on the price asked, the function describing this linear relationship is
[1] y = −2x + 102.
[2] y = −1
2
x + 63.
[3] y = −1
2
x + 51.
[4] y = 1
2
x − 29.

Given : Frieda sells caps at a market. if she charges R50 per cap she sells 26 caps per day. If she charges R80 per cap she sells only 11 caps per day. number of caps sold is dependent on the price asked,
To find : the function describing this linear relationship
Step-by-step explanation:
charges R50 per cap she sells 26 caps per day.
charges R80 per cap she sells only 11 caps per day
x represent the price of a cap
y represent the number of caps
let say linear relationships is
y = ax + b
26 = 50a + b
11 = 80a + b
=> 15 = -30a
=> a = -1/2
26 = 50(-1/2) + b
=> 26 = -25 + b
=> b = 51
y = -x/2 + 51
