Which statements help explain this result? Check all that apply.
12345 [234]

Answer:

The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.

The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.

Exponential growth involves a constant multiplicative rate of change.

Step-by-step explanation:

All that apply in the statements are as follows:

(a) The bottle was ½ full at 11:35 a.m. and doubled again after five minutes, which indicates that the bottle doubled at 11:40 am

(b) The bottle was ¼ full at 11:30 a.m. and doubled twice after 10 minutes. These means that the bottle was ½ full at 11:35 a.m. (i.e. five minutes ago the bottle was at ¼ full at 11:30 am, after five minutes, the which is was ½ full at 11:35 am but later became full at 11:40 am)

(c) Exponential growth involves a constant multiplicative rate of change (1.e. the rates of growth is twice every five minutes)

Calculate the final selling price to the nearest cent and markdown percent to the nearest hundredth percent:
saw5 [17]
There are a couple of ways you can go at this. One way is to look at the price multipliers. For a markdown of d, the price is multiplied by 1-d. For a markup of u, the price is multiplied by 1+u. Your original price is multiplied by ...
  35% markdown: (1 - 0.35) = 0.65
  25% markdown: (1 - 0.25) = 0.75
  18% markup: (1 + 0.18) = 1.18
  15% markdown: (1 - 0.15) = 0.85

The product of all these multipliers is
  0.65×0.75×1.18×0.85 = 0.4889625

As you note, $5600×0.4889625 = $2738.19.

Since this multiplier is 1-d, we can find d as
  1 - d = 0.4889625
  d = 1 - 0.4889625 = 0.5110375
The markdown percentage is this number times 100%:
  markdown% ≈ 51.1%


_____
Alternatively, you can work with your final value to find the percentage change from the original.
  percent change = ((final value) - (original value))/(original value) × 100%
    = (2738.19 - 5600)/5600 × 100%
    = -2861.81/5600 × 100%
    = -0.5110375 × 100% . . . . . . . this should look familiar
  percent change ≈ -51.1%

When the change is negative, it is a markdown (not a markup).
The markdown is 51.1%.
