please answer part B

One of Barbara's favorite things in the whole world is her grandma's banana bread. Barbara has become so obsessed with this bread that she's using her grandma's recipe and making it for her friends. She and her friends have tweaked the recipe so that they can make delicious banana chocolate chip muffins and banana squares, too. They've turned this into a side business, selling their items to local conveniencestores. There's one problem: the baked goods are best when well-ripened bananas are used, They're often available at a reduced price. But when they're not. Barbara has to buy green bananas at full price and wait for them ripen. Here are the typical costs and selling prices for each product. (a) Barbara would love to bake these items seven days a week, but availability of ripe bananas is a constraint. The following quantities of ripe bananas are required for each of the products Barbara makes: banana bread requires 1.25 pounds, mutfins require 1.00 pound, and squares require 0.75 pounds. How much is the contribution margin per pound? (Round answers to 2 decimal places, eg. 15.25) Which product maximizes her profitability, given the constrained resource? maximize(s) her profitability. eTextbook and Media Attempts: 1 of 3 used (b) The local comvenience stores have told Barbara that they can sell as many loaves of banana bread as she can supply, but they can only sell a combined 20 dozen muffins and squares. In a given production period, if Barbara has 25 pounds of ripened bananas to work with, what quantities of each product should she make in order to maximize her profitability?
