Question

Ik It's Either C or D...

Answer 1

Tania has 56 liters of milk. She uses the milk to make muffins and cakes. Each batch of muffin requires 7 liters of milk, and each batch of cakes require 4 liters of milk. Let x be the number of batches of muffins and y be the number of batches of cakes that Tania can make. Which of the following graphs best shows all the possible number of batches of muffins and cakes that Tania can make?

Answer 2

It is obviously D. You can easily check it. For example, in C, the point (9,0) is in the shaped area,but if you put it we get 9*7+0*4=63 liters. However, you have only 56 liters. Thus, you need to scan the area below the graph to make sure that you use at 56 liters milk.
