The cost for a business to make greeting cards can be divided into one-time cost (e.g., a printing machine) and repeated costs (e.g., ink and paper). Suppose the total cost to make 30 cards is $800, and the total cost to make 550 cards is $1,300. What is the total cost to make 1,000 cards?

I don't even know how to find the answer. Someone please help me.

Does any body have the full answers to the test im way behind need to finish this

Please

If the fixed cost is x, and the repeated cost is y per card, then

x+30y=800
x+550y=1300

clearly 520y = 500
Now you know y, and you can find x, and then x+1000y

I suspect a typo, and you must have meant 300 cards or 330 cards or something. Still, follow the steps.

as for Amanda and her father,

Amanda is r
father is 10r

in 3 years, their ages will be
r+3 and 10r+3

so add them up

To find the total cost to make 1,000 cards, we can use the concept of proportionality.

First, let's determine the cost per card for each scenario.

Scenario 1:
Total cost to make 30 cards = $800
Cost per card = Total cost / Number of cards = $800 / 30 = $26.67

Scenario 2:
Total cost to make 550 cards = $1,300
Cost per card = Total cost / Number of cards = $1,300 / 550 = $2.36

Now, let's use these cost per card values to determine the total cost for 1,000 cards.

Scenario 1:
Cost per card = $26.67
Number of cards = 1,000
Total cost = Cost per card * Number of cards = $26.67 * 1,000 = $26,670

Scenario 2:
Cost per card = $2.36
Number of cards = 1,000
Total cost = Cost per card * Number of cards = $2.36 * 1,000 = $2,360

Therefore, the total cost to make 1,000 cards is $26,670 in scenario 1 and $2,360 in scenario 2.

I’m working on it half to do the test myself

Amanda is r years old.Her father is 10 times as old as Amanda.What will their total age be in 3 years time?
