13. Hannah has $482.75 in her savings account. She would like her account balance to be more than $1,250 before she buys a cell phone. Hannah plans to save $85.25 a month. how many months will it be until she can buy a cell phone? (Hint: Write and solve an inequality that represents this situation.)

First I subtracted 250.00-482.75=767.25 and I knew I needed to divide 85.25 and 767.25, but forgot how to.

14. Heidi buys shirts for $20 and resells for $24. What is the percentage of Heidi's mark up?

15. I don't know how to solve this. Help me understand.

14.

4/20 = .2 = 20%

15.
800 - 500 = ?

Figure the percentages on both numbers.

Keep playing with the numbers until you get an answer that makes sense.

15. 800-500=300 now what?

14.thank you

12. wouldn't I do 100%-15%=85% then what do I do with $40 and the 85%

15. Read the problem.

14. You're welcome.
