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>
Answer:Brian got 1.75 lbs of rice per dollar.
Step-by-step explanation: easy way to do these problems is just dividing!! 7 divided by 4 is 1.75. How to double check? Just simply times 1.75 by 4 and you’ll get 7:)
1.5=1 pound 7.5=5 pounds 10.5=7 pounds 16.5=11 pounds
Multiply all of the numbers with each other and then simplify
