Answer:
Juanita will minimize the cost of the dress if she buys it from the Local Department Store
Explanation:
Every 15 minutes cost $14 for Juanita according with the information you should calculate every moved from the work to the shop and multiply by 2 because Juanita spend the same time in every journey.
Every journey and the price of the dress shlud be calculated with the next formula:
= (time by journey * 2*$14) + (the equivalent of 30 minutes shooping)+ dress price
= Local Department Store= (15*2*$14)+($28)+ $100 =$156
=Accross Twon = (30*2*$14)+($28)+ $86 =$ 158
=Neighboring City = (60*2*$14) +($28) +$63 =$199
Answer:
Here we need to find the length of an annuity. We know the interest rate, the PV, and the payments. Using the PVA equation:
PVA =C({1 – [1/(1 +r)t]} /r)
$14,500 = $500{[1 – (1/1.0155)t] / 0.0155}
Now we solve for t:
1/1.0155t = 1 − {[($14,500)/($500)](0.0155)}
1/1.0155t= 0.5505
1.0155t= 1/(0.5505) = 1.817
t = ln 1.817 / ln 1.0155 = 38.83 months
<u>Account will be paid off in 38.83 months.</u>
