Please help me correct the highlighted figures by showing correct formula

Cost Classification Variable and Fixed Costs Contribution Margin Analysis Break-Even Analysis COC Milestone Two - Break-Even Analysis COLLARS LEASHES HARNESSES Sales Price 28 30 35 Fixed Costs 4,028.333 4,028.333 4,201.667 The formula you are using is rounding down instead of up because of the decimal amount. You should change it to roundup instead. For example, you have 213 for collars breakeven but 213 x 18.90 is less than fixed costs. Update the formulas or add 1 to the highlights to fix them.
