Answer:

$80, $48

Step-by-step explanation:

The original price was x.

The price is reduced by 40%. The markdown is 40% of x, or 0.4x.

The actual dollar amount of the markdown is $32.

That means that 0.4x must equal $32.

We set up an equation and solve for x, the original price.

0.4x = 32

Divide both sides by 0.4

x = 32/0.4

x = 80

The original price is $80.

The markdown is $32.

$80 - $32 = $48

The marked down price is $48.

If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)

user100 [1]

Answer:

$h(x)=12x-9$

Step-by-step explanation:

We are given the two functions:

$f(x)=4x-2\text{ and } g(x)=-8x+7$

And we want to find:

$h(x)=f(x)-g(x)$

So, by substitution:

$h(x)=(4x-2)-(-8x+7)$

Simplify. Distribute:

$h(x)=(4x-2)+(8x-7)$

Rearrange:

$h(x)=(4x+8x)+(-2-7)$

Combine like terms. Hence:

$h(x)=12x-9$

A telemarketing company calls telephone numbers chosen at random. It finds that 30% of calls are not completed (the party does n

cupoosta [38]

Answer:

21%

Step-by-step explanation:

Actually there are three levels of process here.

If 100 calls are made only 70 calls are completed (since 30%not completed)

Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.

28 females and 21 males

Out of 28 females 45% buy something = $0.45*28=12.6$

Out of 21 males 40% buy something = $0.4*21=8.4$

Total percent of calls result in a sale = $12.6+8.4=21$

So 21% of calls result in a sale
