2. 10 muffins with chocolate 30 without chocolate
Step-by-step explanation:
Answer:
neither
Step-by-step explanation:
The second and 3rd one can be modeled by by y = 100/x but the first one and the fourth one do not follow that, so the answer is neither. The first and fourth are y = 80/x
Put the values in and you will see the equations for yourself.
One
y = 80/2
y = 40
The 80 came from looking at this as an indirect variation. y = k/x
y = 40
x = 2
y = k/x
40 = k/2 Multiply both sides by 2
40 * 2 = k
k = 80
Two
y = k/x
20 = k/5
k = 20 * 5
k = 100
