Y = 1/2x + b
Plug in the point :)

b = -7
Y = 1/2 -7
Answer:
568 pens.
Step-by-step explanation:
Total number of pens bought = 14 * 50 = 700.
Total pens taken by the workers = 33 * 4 = 132.
Number left = 700 - 132 = 568.
If you mark up 584 by 25%, you get 730. Therefore, the price of the refrigerator after the markup is $730.
