To solve this, write a proportion of Pounds to Cost:
Pounds:     3         x
     Cost: 25.50   42.50

Cross multiply 3 and 42.50, this gives you 127.5
Then, divide by 25.5
This gives you 5.
You can buy 5 pounds with $42.50

Hnmm what's simple, follow this structure- always find the rate(by dividing) first find the rate of 3 pounds and 25.50
3pounds=. 1pound=?
25.50. Try for 1LBS So in order to get this divide 3 by the number that gets it 1 (for one pound)

Which is 3 so 3pounds divided by 3 = the one pound you want. So now divide the 25.50 by 3 to get 8.50. Now this is the problem
1pound=so ____pounds=
8.50. 42.50
All you have to do is divide 42.50 by 8.50 to get 5 FIVE POUNDS EQUAL 42.50 your welcome, I think :)

Marc maxwell took out a simple interest loan at 13% interest for 12 months. his previous balance is $2,681.04. what is the final
V125BC [204]
Simple interest is given by:
S.I.=(PRT)/100
where:
P=principle
R=rate
T=time
from the question:
P=2681.04
R=13%
T=12 months=1 year
thus;
S.I=(2681.04×1×1.3)/100
=$34.85352
The total amount payable will be:
Total amount=principle+interest
=34.85342+2681.04
=$2715.90 This is approximately equal to $2,710.08
