You have got the right equation, ya

remember, you can do anything to an equation as long as you do to to both sides

now combine like terms

3.50p+5.50p=p(3.50+5.50)=p(9)=9p

so
3.50p+5.50p+6=51
9p+6=51
minus 6 both sides
9p+6-6=51-6
9p+0=45
9p=45
divide both sides by 9
(9p)/9=45/9
(9/9)p=5
1p=5
p=5

Answer: The total number of logs in the pile is 6.

Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.

We are to find the total number of logs in the pile.

Let n represents the total number of logs in the pile.

Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with

first term, a = 32 and common difference, d = -6.

We know that

the n-th term of an arithmetic sequence with first term a and common difference d is

$a_n=a+(n-10)d.$
