Question

A baseball bat and 8 baseballs cost $163.25. The bat costs $106.45. What is the cost c of one baseball?

Answer 1

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
