In how many ways can a student answer a five question multiple choice quiz if there are four answer choices for each question and the student never makes the same choice for two consecutive answers

So there are a total of five questions to answer and four choices each question. The following scenario is just an example:

1st question = 4 choices (picks A)

2nd question = 3 choices (picks B, cannot pick A)

3rd question = 2 choices (picks C, cannot pick A, cannot pick B)

4th question = 2 choices (picks D, cannot pick B, cannot pick C)

5th question = 2 choices (picks A, cannot pick C, cannot pick D)

So the total combinations:

C = 4 * 3 * 2 * 2 * 2 = 96 combinations

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
