A store pays $ 23 for each umbrella. The store marks the price at 50%. What is the quantity of the mark?

The quantity of the mark is $11.5.

Step-by-step explanation:

The quantity of the mark can be determined by multiplying the cost of the umbrella by the markup percentage.

Thus,

The quantity of the mark = 23 × 50%

                                          = 23 × 50/100

                                           = 23 × 1/2

                                            = 23 × 0.5

                                             = $11.5

Therefore, the quantity of the mark is $11.5.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
