At the end of 8 years, Anna paid $400 interest for a loan. If the simple annual interest rate was 4%, how much did Anna borrow?

$1,250

Step-by-step explanation:

You can find the answer using the following formula:

i = Prn

i= interest= $400

P= principal

r= rate of interest=0.04

t= time periods= 8

You can replace the values you have in the formula and then, isolate P:

400= P*0.04*8

400=P*0.32

P= 400/0.32

P= 1250

According to this, the answer is that Anna borrowed $1,250.

its a, $1,250! ^>^

Step-by-step explanation:

b: 1 is the final answeer! : )

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
