A red food coloring recipe says, "Mix [tex]4[/tex] tbsp raspberry juice with [tex]3[/tex] tbsp strawberry juice and [tex]2[/tex] tbsp water."

Kiran wants to make [tex]45[/tex] tbsp of red food coloring. He has plenty of water, but he only has [tex]24[/tex] tbsp of raspberry juice and [tex]21[/tex] tbsp of strawberry juice.

What is the most food coloring Kiran can make using the ingredients he has?
