Answer:

Method 1: First expanding then canceling.

We expand the expression on the left side of the equation and get

6p=0.6*5p+0.6*15

6p=3p+9 .

Now we subtract
from both sides and get:

3p=9

$\boxed{p=3}$

Method 2: First dividing then canceling.

We divide the equation by 0.6 and get:

(6p)/(0.6) =(0.6(5p+15))/(0.6) ,

10p=5p+15 ,

now we subtract
from both sides and get

5p=15

$\boxed{p=3}$
