Answer:
Additional bags required = 4
Step-by-step explanation:
Marianne buys number of bags of potting soil = 16
Each bag weighs = [tex]\frac{3}{4}[/tex] pounds
Total weight of 16 soil bags = [tex]16\times \frac{3}{4}=12[/tex] pounds
If Marianne's father requires potting soil = 15 pounds
Amount of additional soil he will require = 15 - 12
                                  = 3 pounds
Therefore, number of additional soil bags required = [tex]\frac{\text{Weight of soil required}}{\text{Soil in each bag}}[/tex]
                                           = [tex]\frac{3}{\frac{3}{4}}[/tex]
                                           = [tex]3\times \frac{4}{3}[/tex]
                                           = 4 bags
Additional bags required by Marianne= 4
