a.which expenses are fixed and which expenses are variable - note some expenses are mixed and therefore need to be split into their variable and fixed components,

d.If sales in 2018 are projected to increase by 10% from 2019 what will the percentage increase in income before taxes from 2018 to 2019 be?
