We are given the functions:
<span>P (d) = 0.75 d --->
1</span>
<span>C (P) = 1.14 P --->
2</span>
The problem asks us to find for the final price after
discount and taxes applied; therefore we have to find the composite function of
the two given functions 1 and 2. To solve for composite function of the final
price of the dishwasher with the discount and taxes applied, all we have to do
is to plug in the value of P (d) with variable d into the equation of C (P).
That is:
C (P) = 1.14 (0.75 d)
C (P) = 0.855 d
or
<span>C [P (d)] = 0.855 d</span>
Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute
So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.
So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.
Which would get us: Mrs. Dean: 150 wpm
Mr. Kovacs: 96(1.25)=120wpm
Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.

bruh whats with the LOLOLOO AHHAA
Given proportional relationship between the number of oatmeal raisin cookies Jane buys, x, and their total cost (in dollars), y shows you that
y=x.
You can check it:
- when x=6 cookies, then y=$6 (x=y);
- when x=8 cookies, then y=$8 (x=y);
- when x=15 cookies, then y=$15 (x=y);
- when x=18 cookies, then y=$18 (x=y).
Answer: y=x.
