First divide the commission by the number sold:

225/5 = 45

300/8 = 37.5 since the commission is a different amount it is not just multiplication so the last two answers are not correct.

Since for 5 the commission was 45 but for 8 it was less than 45, the equation can’t use 45 as a multiplier

The answer has to be E= 25s + 100
