Answer:
It takes $350 14 years to reach $700 with a semiannual interest rate of 2.5%.
Step-by-step explanation:
Giving the following information:
Initial deposit (PV)= $350
Interest rate (r)= 0.05/2= 0.025
Number of perids (n)= ?
Future Value (FV)= $700
<u>To calculate the time required to reach the objective, we need to use the following formula:</u>
<u></u>
n= ln(FV/PV) / ln(1+r)
n= ln(700/350) / ln (1.025)
n= 28.07
28.07/2= 14
It takes $350 14 years to reach $700 with a semiannual interest rate of 2.5%.

Answer:
75
Step-by-step explanation:
let the number of texts equal T
total amount charged by talk company - 15 + 0.1T
total amount charged by mobile service = 0.3T
we are to find the number of texts that would make the charges equal
15 + 0.1T = 0.3T
Collect like terms
15 = 0.3T - 0.1T
15 = 0.2T
T = 15/0.2 = 75
