How do i solve these questions?

1. Find the Break-Even point Fixed costs =$790 Revenues (selling price x# sold) =$1.75180 Variable costs =$81 \# of units =346 a. Calculate the variable cost per unit (variable costs divided by \# of units) VCU=$ b. Find the variable cost margin. (selling price per unit minus variable cost per unit) VCM=$ c. Determine break-even by units: (fixed costs divided by variable cost margin) d. Determine break-even by revenue: (BE units multiplied by selling price) BE=(Roundup)BE(Rev)=$ 2. Find the Break-Even point Fixed costs =$1,058 Revenues (selling price x# sold) =$2.76229 Variable costs =$488 \# of units =621 a. Calculate the variable cost per unit (variable costs divided by \# of units) VCU=$ b. Find the variable cost margin. (selling price per unit minus variable cost per unit) VCM=$ c. Determine break-even by units: (fixed costs divided by variable cost margin) BE=(Roundup) d. Determine break-even by revenue: (BE units multiplied by selling price) BE( Rev )=$ 3. Jennifer owns a bakery and wants to find the break-even point for her chocolate chip cookies. Her selling price per cookie is $1.50. To make 200 cookies, she needs cookie ingredients ($12), chocolate chips ($5), paper bags ($6), rent ($200), and utilities ($27). How many cookies must she sell to break even? 4. Randy is opening a taco stand at a local community event. He is trying to calculate how many tacos he needs to sell in one weekend to reach the break-even point. Rent will cost him $150 and his payroll expense is $200 (both to cover the event). The meat will cost him $160, and the other ingredients will cost him $175 for 200 tacos. He plans to sell the tacos for $5.00 each. How many tacos must Joe sell to reach the break-even point? 5. Rhonda's hat shop has fixed costs of $1,000 per week. She purchases hats that are $2,000 for 400 hats, and she sells the hats for $15.50 each. How many hats does she need to sell to reach her break-even point? 6. Jacob has decided to sell hot chocolate at school. He needs you to find how many cups he needs to sell to break even. He pays $25 per month on the booth to sell the items and $75 per month on labor. Cocoa mix costs $15, and paper cups costs $5. He will be able to make 100 cups of cocoa with those ingredients. If he sells each cup of hot chocolate for $2.50, how many cups will he have to sell to break even? What amount of revenue must Jacob bring in to break even
