For the 10:00 hour of day 4, the dashboard of campaign K-14 showed 9 clicks. The campaign pays 40 cents per click, so the dashboard estimated 360 cents of spend. The invoice for the same clicks charges 8 clicks and 320 cents. Every click passed the invalid-traffic filter, so the reason given in the previous lesson does not explain this gap.
