Answer 1

Answer:

1. Proportional to Mikel's tip.

2. Not proportional to Mikel's tip.

3. Proportional to Mikel's tip.

Step-by-step explanation:

We are told that Mikel gave a $1.32 tip for an order that cost $8.80. We are asked to determine whether or not each given tip is proportional to Mikel's tip.  

Let us compare our given tip and order cost proportions with Mikel given tip and order cost proportion.

1. $\frac{1.32}{8.80}=\frac{2.22}{14.80}$

$0.15=0.15$

We can see that our given proportion is equal to Mikel's proportion, therefore, tip given in first option is proportional to Mikel's tip.

2. $\frac{1.32}{8.80}=\frac{1.86}{10.50}$

$0.15\neq 0.177142857$    

$0.15< 0.18$          

We can see that tip given in second option is greater than Mikel's tip, therefore, it is not proportional to Mikel's tip.

3. $\frac{1.32}{8.80}=\frac{0.78}{5.20}$

$0.15=0.15$  

We can see that our both proportions are equal, therefore, tip given in third option is proportional to Mikel's tip.

Answer 2
