Answer: If Zendaya invests $70 in an account paying a simple interest of 7.3% per year, and no money will be added or removed from the investment, she will have $75.11 in one year.
To calculate the amount of interest earned, you can use the formula:
Interest = Principal x Rate x Time
where
Principal = $70
Rate = 7.3/100 (expressed as a decimal)
Time = 1 year
So the interest earned is:
$70 x 0.073 x 1 = $5.11
To find the total amount at the end of the year, you add the interest to the original principal:
$70 + $5.11 = $75.11
