Question

Mikel gave a $1.32 tip for an order that cost $8.80.

Determine whether or not each tip below is proportional to Mikel's tip.
Proportional to Mikel's tip
Not proportional to Mikel's tip
$2.22 tip for a $14.80 order
$1.86 tip for a $10.50 order
ООО
$0.78 tip for a $5.20 order

Answer 1

To determine whether each tip is proportional to Mikel's tip, we divide the tip amount by the order amount for each tip and compare the proportions. The second and third tips are proportional to Mikel's tip, while the first tip is not proportional.

Step-by-step explanation:

To determine whether each tip is proportional to Mikel's tip, we can calculate the proportion by dividing the tip amount by the order amount for each tip and comparing it to the proportion of Mikel's tip.

1. The proportion for the first tip is $2.22 / $14.80 = 0.15, which is not the same as Mikel's proportion (0.15 is not equal to 0.15).
2. The proportion for the second tip is $1.86 / $10.50 = 0.18, which is the same as Mikel's proportion (0.18 is equal to 0.18).
3. The proportion for the third tip is $0.78 / $5.20 = 0.15, which is the same as Mikel's proportion (0.15 is equal to 0.15).

Therefore, the second and third tips are proportional to Mikel's tip, while the first tip is not proportional.
