Three years ago, claire borrowed money from her father to pay for a class trip. She agreed to pay him 6% simple annual interest on the loan. Now she owes him 90$ in interest, plus the principal amount. How much did Clare borrow? The answer is 500, but how did you get that answer correctly? Step by step can u show me?

Below

Step-by-step explanation:

6% simple annual interest on the loan for 3 years so 6x3=18

So the interest of the whole amount is 18%, so now you got to find what of 18% is 90

This looks like (initial amount)x(number)%=(final amount)

x=initial amount

number%=18

final amount=90

All percentages are just number%/100. So we have either 18/100, or .18 depending on how you want to work it.

So now we do 90÷0.18 which gives you the answer 500

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
