Janesh has savings of $10,950.94. If he can invest this amount to earn 2.4%, how many days will it take for the investment to grow to $11,100? Also calculate the interest earned for this investment. (Do not round intermediate calculations.  Round "Number of days" UP to the next whole day.  Round "Interest earned" to 2 decimal places.)

Janesh has savings of $9625.63. If he can invest this amount to earn 2.8%, how many days will it take for the investment to grow to $9,800? Round to the nearest day.

\(FV = PV ( 1 + i )^{nt}\)
\(9800 = 9625.63(1 + 0.0276162)^{t}\)
\(\frac{9800}{9625.63} = (1 + 0.0276162)^t\)

Take ln on both sides

\(\frac{ln(\frac{9800}{9625.63})}{ln(1 + 0.0276162)} = t\)

t will represent years. Convert to days by using 365 days = 1 year
