Answer:
<h2>y = 0.5x</h2>
Step-by-step explanation:

93% you have to divide the $120 by $12 and then multiply what you get by $12
Step 1: multiply the numbers in front of the parentheses with each term inside the parentheses
15p - 9 = 5p - 5
Step 2: get like terms on the same side
10p = 4
Step 3: divide both sides by 10
p = 4/10
Step 4: simplify
p = 2/5
