Would really appreciate it if I could get help in all 4 parts-

Pure Water Products produces two types of water filters. One attaches to the faucet and cleans all water that passes through the faucet. The other is a pitcher-filter that only purifies water meant for drinking. Revenue and cost information for each product appears below:

? the unit that attaches to the faucet is sold for $80 and has variable costs of $20

? the pitcher-filter sells for $90 and has variable costs of $25

? fixed costs total $945,000

? Pure Water sells 2 faucet models for every 3 pitcher-filters sold

1) Calculate the number of units of the faucet-model that must be sold in order for Pure Water Products to break-even. Enter your answer as a number (i.e., 3,000). Do not use decimals, the $, or type the word units after your answer. 2) Calculate the number of units of the pitcher-filters that must be sold in order for Pure Water Products to earn a profit of $189,000. Enter your answer as a number (i.e., 3,000). Do not use decimals, the $, or type the word units after your answer.

3)Calculate the margin of safety reported by Pure Water Products last year. Do not use decimals in your answer.

4) Assume that last year, the company sold 8,000 faucet model units and 12,000 pitcher-filter units. For the coming year, Pure Water Products is considering investing in an advertising campaign that will increase the sales of the pitcher-filter units by 40% and it is the companys goal to increase the coming years profits by 50% over last years profits. However, if this advertising campaign is undertaken, sales of the faucet model are expected to fall by 5% because some customers who would have purchased the faucet model will instead purchase the pitcher-filter. Calculate the maximum amount the company can spend on the advertising campaign. Do not use decimals in your answer.
