Answer:
(b) S = 15,210
Step-by-step explanation:
The common ratio is ...
r = 1369/1521 ≈ 0.90
So, the sum is ...
S = 1521/(1 -r) = 1521/0.10 = 15,210 . . . . . sum of the series

Answer:
The cost must be $32 since that is the only cost possible for the 1st deal
Step-by-step explanation:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal
Answer:
The answer to your question is 35x - 35y + 21
Step-by-step explanation:
Data
Simplify 0.5(20x - 50y + 36) - 0.25(-100x + 40y - 12)
Expand
10x - 25y + 18 + 25x - 10y + 3
Group like terms
(10x + 25x) + (-25y - 10y) + (18 + 3)
Result
35x - 35y + 21
The answer is the last choice
