<h3>Given</h3>

burned : unburned = 1 : 3

<h3>Find</h3>

burned/total as a percentage

<h3>Solution</h3>

burned : total = burned : (burned + unburned) = 1 : (1+3) = 1 : 4

As a fraction, this is 1/4 = 0.25 = 25%

25% of the total cookies were burned.

_____

"%" is a fancy way to write "/100". You know from place value that 0.25 (twenty-five hundredths) is 25/100, so that can also be written as 25%.

If the typical balance on Lucy's credit card is $650 and the interest rate (APR) on her credit card is 18%, how much in interest
Mariana [72]

$9.75

<h3>Further explanation   </h3>

Given:  

  • The typical balance on Lucy's credit card is $650.
  • The interest rate (APR) on her credit card is 18%.

Question:  

How much in interest would you expect Lucy to be charged in a typical month?

The Process:  

This problem includes the type of determining simple interest.

\boxed{ \ I = P \times r \times t \ }  

where,

  • I = simple interest
  • P = principal (initial amount)  
  • r = annual interest rate
  • t = time (in years)

This time we will find out how much in interest we would expect to be charged in a typical month.

The data is as follows:

  • P = 650
  • r = 18% or \frac{18}{100} or 0.18  
  • t = \frac{1}{12} year  (one month)

Let us calculate how much in interest we would expect to be charged in a typical month.

\boxed{ \ = 650 \times \frac{18}{100} \times \frac{1}{12} \ }  

\boxed{ \ = 65 \times \frac{3}{10} \times \frac{1}{2} \ }  

\boxed{ \ = \frac{195}{10} \times \frac{1}{2} \ }  

\boxed{ \ = \frac{97.5}{10} \ }  

\boxed{ \ = \frac{975}{100} \ }  

Thus the amount of interest we would expect Lucy to be charged in a typical month is $ 9.75.

What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:

3, 2^2, 2^5, 3^2

Your LCD must include the following factors:  3^2 and 2^5, or 9 and 32.  Multiplying these together results in the correct LCD 9*32=288.

Check:  Is 288 divisible by 3?  Yes.  The quotient is 96.
Is 288 divisible by 4?  Yes.  Is 288 divisible by 32?  Yes.  Is 288 divisible by 9?  Yes.
