Alocal charity earns money to donate to flood victims. it receives $200 per day in cash donations and $150 in pledges but must spend $75 per day in operating costs. after how many days, d, will the charity have enough money to make at least a $1000 donation? a. 200+150-75> 1000 b. 200d+150-75d> 1000
c. 200d+(150-75)d> 1000
d. 200d+150-75d> 1000d

Just took the quiz and the correct answer was B. 200d + 150 - 75d > 1,000

Step-by-step explanation:

As per the question statement, a₁ is -6.25 and common ratio (r) is 1.25.

Therefore, the six terms of finite sequence would be as per the following equation . Thus, the series would be

a1 = -6.25a2 = -6.25*r = -6.25*(1.25) = -7.8125a3 = -6.25*r^2 = -6.25*(1.25)^2 = -9.765625a4 = -6.25*r^3 = -6.25*(1.25)^3 = -12.20703125a5 = -6.25*r^4 = -6.25*(1.25)^4 = -15.2587890625a6 = -6.25*r^5 = -6.25*(1.25)^5 = -19.073486328125

So the points on the graph will be on following points,

(1, -6.25), (2, -7.8125), (3, -9.765625), (4, -12.20703125), (5, -15.2587890625), (6, -19.073486328125).

The graph would look like as attached.
