A bank loans a customer \$35,000 for a period of 8 yrs. The simple interest rate of the loan is 10.7%.What is the total amount that the customer will need to pay the bank over the 8 yrs.

You could use this formula:

Interest = principal * rate * time

I = 35,000 * 0.107 * 8

Add the interest to the principal to get the total amount.

The interest for one year is \$3,745.

Multiply that by 8.

A compound is made up of various elements totaling 90 ounces. If the total amount of zinc in the compound is 1 ounce, what percent of the compound is made up of zinc? Is it 1%

• Math 8th grade - ,

No. 1% of 90 ounces is 0.9 ounce.

You could set up a proportion and cross multiply.

1 / 90 = x / 100
90x = 100
x = 100 / 90
x = 1.11111

Let's check that. 1 ounce of 90 ounces is 1.11%

011111 * 90 = 0.99999 = 1

Sue, thanks for helping my daughter Alyssa she has ADD and she is struggling in school. She has a IEP
but she seems to score low on test and quiz's would i be asking to much if i requested that her teachers give
her a study guide a week in advance?

That's an excellent idea. Or at least, they may be able to provide her with a syllabus for the next week or so.

When I taught middle school, at the start of each unit I gave each student a syllabus, outlining the information covered and the homework for each day.
