Answer:
7.5
Step-by-step explanation:
20 rolls : 5 tbsps
this means that 1 roll : 0.25 (5 / 20)
to figure out how much butter for 30 rolls, we must multiply 0.25 by 30 = 7.5
So, we need 7.5 tablespoons of butter for 30 rolls.
Hope this makes sense. If you require further explanation, don't hesitate to ask.
