Answer:
m = 2500b
Step-by-step explanation:
As instructed,
let b = number of boxes sold
let m = total money made.
The total money made, is a function of the number of boxes sold.
Let me break this down:
There are 100 pencils in a box;
if they sold only one box, they will get 100 X $25 = $2500;
if they sold two boxes, they will get 200 X $25 = $5000;
if they sold three boxes, they will get 300 X $25 = $7500;
Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25
representing this using the variables we were given, we have
m = 100b X 25
hence
m = 2500b
