Answer: $120000
Step-by-step explanation:
Share of voice refers to the measure of the exposure that a particular business gets when it's being compared to other competitors. The share of market is the percentage of a market that a company earns.
From the information given, since 60% of the market sales equate to $240000 spent a year, then in order to achieve a market share of 30%, ½ of $240000 will be spent which is $120000. Therefore, Great Catch should be prepared to spend at least $120000 if it hopes to achieve a market share of 30 percent.
