To calculate the interest Zoey will need to pay on her smartphone purchase, we first need to find out the amount of interest for the $800 purchase at a 30% annual interest rate.
Interest = Principal x Rate
Interest = $800 x 30%
Interest = $800 x 0.30
Interest = $240
So, Zoey will need to pay $240 in interest on her smartphone purchase.
To find out how much her smartphone will end up costing her in total, we need to add the interest to the original purchase price.
Total cost = $800 (purchase price) + $240 (interest)
Total cost = $1040
Therefore, Zoey's $800 smartphone will end up costing her a total of $1040 if she takes a year to pay it off.
Interest = Principal x Rate
Interest = $800 x 30%
Interest = $800 x 0.30
Interest = $240
So, Zoey will need to pay $240 in interest on her smartphone purchase.
