Answer:
y($) = 405- 20x
Step-by-step explanation:
Number of short driveways = x
Number of long driveways = 9-x
Fee per long driveway = $45
Fee per short driveway= $25
Total amount = y
y ($) = 25x + 45 (9-x)
= 25x + 405 -45x
= 405- 20x
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.
Total distance walked = 1500 meters.
Dakota's r
ate is 60 meters per minute.
The equation for distance walked over time = r
⋅
t
.
Therefore the distance walked over t
ime = 60
⋅
t
The equation for distance remaining (let's call it R is 1500
−
(
60
⋅
t
).
so the remaining distance to walk after a time t can be written as
R
=
1500
−
(
