Answer 2

I know it's a lot but I'm really stuck

Answer 3

the unit price is a simplified fraction. if we want the unit price of price per cup we set up a fraction such that we have the price over the amount of cups
\(\dfrac{$54}{6 \text{ cups}}=\dfrac{$9}{1cup}\)

Answer 4

Which part is that for

Answer 5

I said unit price there's only one part that asked for unit price

Answer 6

oh okay

Answer 7

2:1 yellow:blue
part a:
There are twice the amount of yellow cups of paint as there are blue cups of paint.

Answer 8

part b:
since we want 2 yellow + 1 blue
2y+1b

we wanna know how much blue gets added to 1 cup of yellow so we divide both sides by 2
y+\(\dfrac{1}{2}b\)
