Eight months ago, toris parents put $5000 into a savings account that aerns 3% interest. Now, her dentist has suggested that she get braces.

A.If the interest is calculated each month, what is the monthly interest rate?

3%/ 12 months = 0.25%/ month

B. if Toris parents use the money in thier savins account, how much do they have?

$5000 + 0.25*(8 months)= $5,100

C. if toris dentist has suggested braces 3 months ago, how much money would have been in her parents' savings account?

$5000 + 0.25*(5 months)= $5,062.50

D. Toris dentist says she can probably wait up to 2 months before having the braces fitting. How much will be in her parents' savings account if she waits?

$5000 + 0.25 * (10 months)= $5,125


i just wanted to know if i did this problem right

$5000 + 0.25*(8 months)= $5,100 no ...
A = 5000(1+0.0025)<sup>8</sup> = $5100.87


C. if toris dentist has suggested braces 3 months ago, how much money would have been in her parents' savings account?

$5000 + 0.25*(5 months)= $5,062.50 no ...
same reason as part (b)
