Answer 2

The amount of interest Zoey will need to pay is $0, as it is not specified in the question.

Her $800 smartphone will end up costing her $800 if there is no interest involved.

Answer 3

To calculate the interest Zoey will need to pay on her smartphone purchase, we first need to determine the amount of interest based on the 30% annual interest rate.

Interest = Principal x Rate
Interest = $800 x 30% = $800 x 0.30 = $240

Therefore, Zoey will need to pay $240 in interest on her smartphone purchase if she takes a year to pay it off.

To calculate the total cost of the smartphone including the interest:
Total Cost = Principal + Interest
Total Cost = $800 + $240 = $1040

Therefore, her $800 smartphone will end up costing her $1040 in total.
