Answer:  The correct option is (C) 15\dfrac{1}{4}.

Step-by-step explanation:  Given that Jane has 3\dfrac{3}{4} dozen boxes of envelopes and she ordered 11\dfrac{1}{2} dozen more.

We are to find the total dozen of boxes that Jane will have.

The total dozen of boxes that Jane will have is equal to the sum of dozen of boxes she has now and the dozen of boxes she has ordered.

Therefore, the total dozen of boxes Jane will have is given y

3\dfrac{3}{4}+11\dfrac{1}{2}\\\\\\=\dfrac{15}{4}+\dfrac{23}{2}\\\\\\=\dfrac{15+46}{4}\\\\\\=\dfrac{61}{4}\\\\\\=15\dfrac{1}{4}.

Thus, the total dozen of boxes that Jane will have is 15\dfrac{1}{4}.

Option (C) is correct.

Hi there:-)

She has=3+3/4=15/4
She ordered=11+1/2=23/2
Now how many she has in all
(15/4)+(23/2)=15 1/4 ...answer

15 1/4 means 15+1/4=15.25

Hope it helps

spayn [35]
The equation is:
h  + c = 345 \\  \\ c = 2h
Replace c with 2h:
h + 2h = 345 \\  \\ 3h = 345
Divide both sides by 3:
h = 115
