Answer:
(a) 0; 0
(b) $150 per hour; $16.67 per hour
(c) (b) $150 per hour; $53.57 per hour
Explanation:
(a) Number of hours = 125
Marginal cost = 0 (since service is cost less upto 200 hours)
Average cost = 0
(b) Number of hours = 225
Marginal cost = $150 per hour
Total cost = $150 × (225 - 200)
= $150 × 25
= $3,750
Average cost = Total cost ÷ Number of hours
= $3,750 ÷ 225
= $16.67 per hour
(c) Number of hours = 325
Marginal cost = $150 per hour
Total cost = $150 × (325 - 200)
= $150 × 125
= $18,750
Average cost = Total cost ÷ Number of hours
= $18,750 ÷ 325
= $53.57 per hour

Answer:
Explanation:
This is an Ordinary Annuity question. You can solve this using a financial calculator. I'm using (TI BA II Plus)
N; duration = 20
I/Y ; interest rate per year = 8.5%
PMT ; recurring annual payment = 70,000
FV; Future value = 0 (In solving annuities, use 0 if not given)
then CPT PV = ?
PV = 662,433.563
Therefore, your friend needs to have $662,433.56
