C= 1,800- dailey fixed cost
2,200 (x) pianos in one day
c= 1,800 +2,200 (2)=
cost= 6,200
D) f(n) = 3 + 4(n-1)
3 = 1st term
4 = common difference among the terms
n = term number you are looking for.
To check: 3, 7, 11, 15, ...
f(1) = 3 + 4(1-1) = 3 + 4(0) = 3 + 0 = 3
f(2) = 3 + 4(2-1) = 3 + 4(1) = 3 + 4 = 7
f(3) = 3 + 4(3-1) = 3 + 4(2) = 3 + 8 = 11
f(4) = 3 + 4(4-1) = 3 + 4(3) = 3 + 12 = 15
Answer:
y=25x+50
Step-by-step explanation:
The rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental.
let x be day of rental n y be the total cost of rental
with 0 day (x=0), the one time fee means y=50 which is the y-intercept
$25 per day means the slope is 25
combining y = 25x + 50
