At a concession stand, one hot dog and one hamburger cost $3.75 ; one hot dog and cost $12.25 . Find the cost of one hot dog

raketka [301]

The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.

<h3>How to calculate the information?</h3>

Let hotdogs = h

Let hamburger = x

The expression will be:

h + x = 3.25

h + 7x = 12.25

Subtract the functions

6x = 9

x = 1.5

Therefore, hot dogs will be:

= 3.25 - 1.5

= 1.75

Arley’s Bakery makes fat-free cookies that cost $1.50 each. Arley expects 30% of the cookies to fall apart and break. Assume tha

Lesechka [4]

First we see the cost of making 200 cookies:
(200) * (1.50) = 300 $
Then, we see the amount of cookies that are not broken:
(200) * (0.30) = 60
200-60 = 140
Arley wants to 50% markup on cost and produces 200 cookies:
(300) * (1.50) = 450 $
Arley can sell the broken cookies for $ 1.40 each:
(1.40) * (60) = $ 84
For each unbroken cookie the price will be then:
(450-84) / (140) = 2.61 $
Answer:
Arley should charge $ 2.61 for each unbroken cookie
