					                   9r+7+3(8p+7r)+15
= 9r + 7 + 24p + 21r +15
= 24p + 30r + 22
hope it helps
					                
					             = 9r + 7 + 24p + 21r +15
= 24p + 30r + 22

					                   We can simplify it to get something equivalent. 
9r+7+3(8p+7r)+15
Distribute the 3.
9r+7+24p+21r+15
Combine like terms.
7+15=22
9r+21r=30r
24p=24p
SO,
30r+24p+22 <== equivalent expression
I hope this helps!
