I like to start by dividing the given number by 2, unless a larger factor is evident.
1386 = 2(693). It's pretty obvious that we can divide 693 by 3: 693=3(231).
Then we have 1386 = (2)(3)(231). Try the same procedure. Does 231 have any integer, prime factors? See how far you can take this factoring.
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
The square root of 64 is 8 since 8*8 or 8^2 equals 64
The answer is 5+8x i think
