Question

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.

Answer 1

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

Answer 2

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
