Question 1:
Price per milliliter
Small $4.50 / 250ml
Medium $9.95 / 500 ml
Large $16.95 / 1000 ml
Question 2:
$9.95 / 500 ml > $4.50 / 250ml > $16.95 / 1000 ml
Question 3 - 4:
$4.50 / 250ml = ($4.50 * 6) / (250ml * 6 ) = $27 / 1500ml = 0.018
$9.95 / 500 ml = ($9.95 * 3) / (500 ml * 3) = $29.85 / 1500ml = 0.019
$16.95 / 1000 ml = ($16.95 * 3) / (1000 ml * 3) = $50.85 / 1500ml = 0.0339
( Use the first one for question 3 and the second for question 4)
$4.50 / 250ml would be the cheapest way to get 1500ml.
$9.95 / 500ml would be the most expensive way to get 1500ml.
I hope this helps you! Tell me if I'm wrong!
If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2
