Since Jon has worked for three weeks, we can multiply his weekly earnings by 3, because that’s the amount of weeks he’s earned money.
$15.50 x 3 = $46.50
From there, since Jon bought a video game, we know that he spent his money, meaning we’ll have to subtract the amount he paid for the video game from his total.
$46.50 - $42.39 = $4.11
Therefore, Jon has $4.11 left of his earnings.
Hope this helped! :)
