Please help on th question plz.

Answer 1

20%

Explanation:

Skills needed: Percents, Subtraction with Percents

1) When looking at Shira's graph, we know that:

1. 35% of her paycheck is used on Rent
2. 30% of her paycheck is used on Car
3. 15% of her paycheck is used on Savings

2) We need to find the percent amount she uses for bills. Now, the circle graph represents One-Whole, or in other words: 100% total

This graphs shows all of her expenses, 100% of it

3) So based on this, we can easily solve for the Bills. Let's make the bills a variable
`b`

A variable is a letter or symbol used to show a specific value we are usually trying to find in a problem.

4) So, we can make an equation:

--> 30% + 30% + 15% +
`b`% = 100%

35% + 30% + 15% = 80%

So based on the step above: 80% +
`b`% = 100%

Subtract 80% from both sides, and you will get:
`b`% = 100% - 80%

100% - 80% = 20%

So then
`b`% = 20%

Therefore 20% is your answer

Important note: Subtracting with percentages is very similar to subtract with regular numbers, except they contain a percent-sign (%) after the numbers.

Hope this helps and have a nice day!! :) :] :D
