Monty loaned Betty $500 at an annual interest rate of 8%. If no payments are made, what is the total amount owed at the end of the first year?
| $520 | |
| $535 | |
| $545 | |
| $540 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $500
i = 0.08 x $500
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $500 + $40a(b + c) = ab + ac defines which of the following?

distributive property for division |
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
