## Algebra 1

Let x be the number of jars Cost of a jar: $\frac{4}{5}$(3.00)+$\frac{1}{5}$(6.00) =2.4+1.2=3.6 Expense is the cost of number of jars +the cost of material =>Expense=y=3.6x+70 Income: y=5x To break even, expense is equal to income 3.6x+70=5x => 70=1.4x => x=50 (Divide both side by 1.4 Therefore to break even, the person has to sell 50 jars.
