Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)
b. 8 because Total Pieces Sold=60
Pieces contributed by the cafeteria=20
Pieces contributed by the clubs=x
We can solve this problem by creating an equation to relate these terms:
Total Pieces Sold= (pieces contributed by the cafeteria) + (pieces contributed by the clubs)
Our equation is therefore: 60=20+x. We solve for x:
60-20=x
40=x
This means the clubs contributed 40 pieces. To find out how many pies that equals, we can use the relationship:
(40 pieces)/(y pies) = (5 pieces)/(1 pie). Solve for y:
(1)(40)=(5)(x)
(40/5)=8
