Answer: $7787.99
Step-by-step explanation:
We know that the formula to find the periodic payment on an annuity is given by :-
, where PV is the present value , r is the rate of interest ( in decimal ) and n is the number of payments.
Given : Present value : $36000
Rate of interest = 8%=0.08
Time period = 6 years
Then , the periodic payment will be :-
Hence, the payment size is $7787.99.
Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
The answer is B. x > -22
-5x + 20 < 130
-5x < 130 - 20
-5x < 110
-5x/-5 > 110/-5
x > -22
