Jermaine Enterprises decided to increase spending on its marketing budget and see if it could gain market share.

Promotion dollars appear to have generated the best results. Jermaine spent $$2\mathrm{.}4$ million on promotions and generated $$57\mathrm{.}5$ million in new sales directly attributed to the promotions.
