Answer:
B. $444.44
Step-by-step explanation:
We have been given that Andrew buys a home entertainment system from an electronics store offering 0% interest for 18 months. This means if she pays monthly payment she will not be charged with any interest for 18 months.
As Andrew will make 18 payments in 18 months, so payment for each month can be found by dividing total cost of entertainment system by 18.
Therefore, Andrew should make a monthly payment of $444.44 to avoid paying deferred interest charges for the $8,000 system. and option B is the correct choice.
Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is or 1/9 to the 3rd power.
<em>Down is a formula I made!</em>
Main number: 1/9
Repeating how many times: 3
Expression:
Therefore, 1/9 to the 3rd power is 1/729.
