Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0.75p, where p is the original price of the laptop. He also knows he has to pay 8% sale's tax on the laptop. The price of the laptop with tax is f(c) = 1.08c, where c is the sale price of the laptop.Determine the composite function that can be used to calculate the final price of Ray's laptop by solving for f[c(p)].

f[c(p)] = 1.83p
f[c(p)] = 1.83cp
f[c(p)] = 0.81p
f[c(p)] = 0.81cp

Answers

Answer: $f[c(p)]=0.81p$

Step-by-step explanation:

Given: Ray is purchasing a laptop that is on sale for 25% off.

The function that represents the sale price of his laptop :

$c(p) = 0.75p$ , where p is the original price of the laptop.

The price function of the laptop with tax :

$f(c) = 1.08c$ , where c is the sale price of the laptop.

Now, consider the composite function that can be used to calculate the final price of Ray's laptop .

$\text{ i.e. }f[c(p)]=f[0.75p]\n\n\Rightarrow f[c(p)]=1.08(0.75p)\n\n\Rightarrow f[c(p)]=0.81p$

c(p) = 0.75p where p is the original price of the laptop
f(c) = 1.08c where c is the sales price of the laptop

the composite function is:

f(c(p)) = 1.08(0.75p)
f(c(p)) = 0.81p

Calculator What is the area of this parallelogram? 44 cm²

O 55 cm²

O 99 cm²

O220 cm²

Answers

The calculated value of the area of the parallelogram is 99 square cm

Calculating the area of the parallelogram

From the question, we have the following parameters that can be used in our computation:

The parallelogram

Where we have

Height = 11 cm

Base = 5 cm + 4 cm = 9 cm

The area of the parallelogram is calculated as

Area = Base * Height

Substitute the known values in the above equation, so, we have the following representation

Area = 11 * 9

Evaluate the product of 11 and 9

So, we have the following representation

Area = 99

Hence, the area of the parallelogram is 99 square cm
