Step One

Develop a formula for the perimeter.

Argument

What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.

The "perimeter" [Circumfrence] of a whole circle = 2*pi*r

We are told that whatever you call this the perimeter is 8pi + 16

Step Two

Set up the equation

8pi + 16 = 2*pi*r + 4r Including the line connecting these two.

Step Three

Take out the common factors on the left and right.

8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2

8 = 2r Divide by 2

4 = r

Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%. He sells each candy var for 175% of what he paid before tax. ho

Zepler [3.9K]

Answer:

Cost price of each candy = $0.80, Selling price of each candy = $1.40

Step-by-step explanation:

Given:

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%.

He sells each candy var for 175% of what he paid before tax.

Question asked:

How much does he buy each candy bar for ?

How much does he sell one for ?

Solution:

By unitary method:

Cost of 50 packs of candy bars = $40

Cost price of 1 pack of candy bars = $\frac{40}{50} =\$0.8$

Cost price of each candy = $0.80

Thus, he buy each candy bar for $0.80

Now:-

As he sells each candy var for 175% of what he paid before tax:-

Selling price of each candy = 0.80 $\times$ 175%

= $0.80\times\frac{175}{100} =\frac{140}{100}=\$1.4$

Thus, he sell one candy for $1.40
