The profit from selling y units = 4y -2
4 X ( this profit ) = 16y - 8

Quantity A = 16y-8
Quantity B = 16y -4

Given y>0 ,


Quantity A ? Quantity B
16y - 8 ? 16y -4
Adding 4 both sides
16y - 4 ? 16y
If y>0 , 16y-4 < 16y

Hence, Quantity B is greater

Question:
The profit from selling y units of a product is given by the formula 4y − 2, where y > 0.
Quantity A: 4 times the profit from selling y units
Quantity B: 16y - 4


Solution:
Quantity A: 4 times the profit from selling y units = 4(4y - 2) = 16y - 8
Quantity B: 16y - 4

Thus, in Quantity A, 8 is subtracted from 16y; whereas in Quantity B, only 4 is subtracted from 16y
Thus, Quantity B is greater
