Question

10) Which has the lowest price per ounce?

please refer to the chart above <3​

Answer 1

The lowest price per once is: "Don's store" $ 0.101

Explanation:

You have to apply a 3 way rule

so:

1) 60 oz ----- $6.50

1 oz ----- =(1 oz X $6.50)/ 60

= $0.108

2) 54 oz ----- $5.50

1 oz ----- =(1 oz X $5.50)/ 54

= $0.101

3) 48 oz ----- $5.61

1 oz ----- =(1 oz X $5.61)/ 48

= $0.116

4) 40 oz ----- $4.50

1 oz ----- =(1 oz X $4.50)/ 40

= $0.112
