Start with the Search Advertising tab $($which should be the default$).$

For the first scenario, set your budget $($Search Ad Cost$)$ at $$500,000,$ set your Ad ClickThrough$-$Rate $($CTR$)$ at $0\mathrm{.}30\%,$ set your Cost$-$Per$-$Click at $$1\mathrm{.}50,$ and set your Sales Conversion Rate at $1\mathrm{.}50\%.$

What does the Margin of the Sale need to be to break$-$even on your Search Ad ROI $($hint: adjust your Margin $($$$)$ setting until your Search Ad Return on Investment at the bottom of the activity box $=0\mathrm{.}0\%)?$

Also, at these settings, what is your Cost per Acquisition? $($if this seems like a trick question, then you probably have the correct answer$)$
