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.

$2.22 tip for a $14.80 order; Proportional or not?

$1.86 tip for a $10.50 order; Proportional or not?

$1.86 tip for a $10.50 order; Proportional or not?

1. Proportional

2. Not proportional

3. Not proportional

Step-by-step explanation:

Let's see what percentage of the $8.80 order is the $1.32 tip.

To find what percent a p[art is of a whole, divide the part by the whole and multiply by 100%.

$1.32/$8.80 * 100% = 15%

Mike's tip was $15% of the total.

1. $2.22 tip on $14.80 order

15% of $14.80 = 0.15 * $14.80 = $2.22

Tip is proportional

2. $1.86 tip on $10.50 order

15% of $10.50 = 0.15 * $10.50 = $1.58

Tip is nor proportional

3. Same as option 2 above.
