If it costs $4 to make 3 cards, and $6 to make 7 cards, what's the total cost of making 25 cards?

$24 im pretty sure

Step-by-step explanation:

Step-by-step explanation:

7+3 = 10 $4+$6=$10

so it costs 10 dollars to make ten cards, how many times does 10 go into 25? 2

so $20 so far, I'm not that good at explaining.

Now with the remaining 5 cards that we have to make, we add three and have 24$ for 23 cards. Now with the remaining two cards we add $1.50.

because 2 x 1.50 = 3

so $25.50 for 25 cards I think...

I really hope I'm right and I hope this helps!

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
