Question

The grocery store makes a 20% profit on baked goods. The profit for baked goods last month was $600. What was the total sales for baked good last month?  The grocery store pays a 15% tax on alcohol sales. The total tax paid last year was $3,750. What was the total sales for alcohol last year?

Answer 1

Let x = total sales of baked goods      remember 20% = .20 as a decimal

 

so the equation would be .20x = $600

 

divide both sides by .20

 

                                      .20x/.20 = $600/.20

            

                                                 x = $3000 the total sales of baked goods

 

CHECK   20% times $3000 = .20 times $3000 = $600    this is the desired profit.√

 

 

 

let y = total sales of alcohol      15% tax = .15

 

so the equation would be            .15y = $3750

 

divide both said by .15

 

                                                   .15y/.15 = $3750/.15

 

                                                              y = $25000 the total sales of alcohol

 

CHECK     15% times $25000 = .15 times $25000 = $3750     this is the desired tax paid√
