Answer:
20%
Explanation:
Skills needed: Percents, Subtraction with Percents
1) When looking at Shira's graph, we know that:
- 35% of her paycheck is used on Rent
- 30% of her paycheck is used on Car
- 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
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% +
% = 100%
35% + 30% + 15% = 80%
So based on the step above: 80% +
% = 100%
Subtract 80% from both sides, and you will get:
% = 100% - 80%
100% - 80% = 20%
So then
% = 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
