See a solution process below:

Explanation:

Let's call the cost of 1 baseball: #b#

We can then write the follow equation for the word problem as:

#$106.45 + 8b = $163.25#

We can now solve for #b# to find the cost of 1 baseball:

#$106.45 - color(red)($106.45) + 8b = $163.25 - color(red)($106.45)#

#0 + 8b = $56.80#

#8b = $56.80#

#(8b)/color(red)(8) = ($56.80)/color(red)(8)#

#(color(red)(cancel(color(black)(8)))b)/cancel(color(red)(8)) = $7.10#

#b = $7.10#

One baseball cost $7.10
