Need to find the break$-$even point in part b$?$

Problem $6$A$-5($Algo$)$

A firm is selling two products, chairs and bar stools, each at $$50$ per unit. Chairs have a variable cost of $$30,$ and bar stools $$20.$ Fixed

cost for the firm is $$21,000.$

a$.$ If the sales mix is $1$:$1($one chair sold for every bar stool sold$),$ what is the break$-$even point in dollars of sales? In units of chairs and

bar stools?

Note: Round up your unit answers to a whole number before calculating the break$-$even point and round the break$-$even point

to the nearest whole number.

b$.$ If the sales mix changes to $1$:$4($one chair sold for every four bar stools sold$),$ what is the break$-$even point in dollars of sales? In units

of chairs and bar stools?

Note: Round up your unit answers to a whole number before calculating the break$-$even point and round the break$-$even point

to the nearest whole number.
