A store sells 12-packs of ballpoint pens for $1.09 each and composition books for $2.79 each. Cindy buys m packs of ballpoint pens and n composition books. The store offers a 5% discount for every 50th customer who makes a purchase. If Cindy gets the 5% discount, which expression will represent Cindy’s bill? A.
0.05 − 1.09m + 2.79n
B.
1.05 + 1.09m + 2.79n
C.
1.05(1.09m + 2.79n)
D.
0.95(1.09m + 2.79n)

D

Step-by-step explanation:

100% is 1-

5% is 0.05

1-0.05 = 0.95

0.95(1.09m + 2.79n)

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
