Pen=x
Pencil=y
y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $

Answer:
d = 363/8
Step-by-step explanation:
Let's write this as a fraction:
8 1/4 2
------------- = -------
d 11
One way in which this could be approached would be to interchange 'd' and '2:'
8 1/4 d 33 d
------------- = ------- or -------- = ---------
2 11 4(2) 11
Multiplying both sides by 11 isolates d:
33(11) 363
-------- = d, or d = ----------
8 8
D is your correct answer, the more trials you do, the closer you get to
an accurate probability. Think of it like scientific trials. The less
you do, the further you are from creating an accurate law of science,
but something that has been tested over and over again is more likely to
be accepted as an accurate fact.
