Answers

1) 33+a=12a
33 = 11a
33/11 = a
a = 3

2) -6n+2=4n-5
2 = 10n-5
7=10n
n = 7/10
n = 0,7

3) 2.4b-7=b+15.4
2.4b=b+22.4
1.4b=22.4
b = 22.4/1.4
b = 16

An office supply store sells report covers at 3 for $0.96. If the rate remains the same, how much will 10 covers cost? Please show your work. Explain.

Answers

We can use a proportion to figure this out.If we get 3 for 0.96 (3/0.96) how many can we get for 10 (10/x)?So far it should look like this 3/0.96= 10/xNow we cross multiply. 0.96 times 10 is 9.6 and 3 times x is 3x. To get rid of the 3 we divide by it to get x alone. So 9.6 divided by 3 equals 3.2. I hope that this helps you. Try writing out the proportion of you don't understand! :)

Which term is a word for an initial amount of money that is borrowed or invested?

Answers

Answer:

The term which is used to define an initial amount of money that is borrowed or invested is:

                    Principal amount

Step-by-step explanation:

It is the amount or sum of money that is borrowed or invested for some purpose.

In context of borrowing a person borrows this amount and at the time of repaying his loan he has to pay this amount and the extra amount is to be paid which is the interest on the loan.

Similarly in context of investment a principal amount is to be invested and then the interest is gained on the amount.
The answer is Principal.
