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
