Well, each one takes two minutes, regardless of how many brothers there are. If it takes 2 minutes per paper, then the answer is simply 147*2. Which is 297 minutes. Even if one of them was delivering papers, the answer would be the same. These extra numbers are put in there to confuse you. Dont forget that, be careful what you read.
Steps:
1. Do a proportion
X/62= 81/100
2. Do 81 times 62 which is 5,022
3. Now divide 5,022 by 100 which is 50.22
4. Your answer is 50.22
A local hamburger shop sold a total of 712 burgers on Tuesday
There are 62 more cheeseburgers than hamburgers
let cheeseburers = c
let hamburgers = h
h + 62 = c
c + h = 712
Plug in h + 62 for c
(h + 62) + h = 712
2h + 62 = 712
2h + 62 (-62) = 712 (-62)
2h = 650
2h/2 = 650/2
h = 325
There are 325 hamburgers sold on Tuesday
c = 325 + 62
c = 387
<em>There are 387 chesseburgers sold on tuesday </em>(in case you were wondering)
hope this helps
f(x)=40
x=8
so if x=2 it would be 40/8 which is 5
