Set a proportion

$8/12 bags= x/30 bages
12*2.5=30
8*2.5=20=x

Final answer: $20

Answer:

$20

Step-by-step explanation:

We have given that : 12 bags cost $8  

To find: cost of 30 bags  

Solution :  We know,  12 bags cost =$8  

                so,  1 bag cost =$ [tex]\frac{8}{12}=\frac{2}{3}[/tex]


                 now, 30 bags cost = $ [tex]30\times\frac{2}{3}[/tex]


                hence,  30 bags cost  =$20
