Question

Mariane buys 16 bags of potting soil for her father that comes in 3/4 pound bags. Part 1 How many pounds of potting soil does Marianne buy? Use the drop downs to put the correct number into the box to complete the statement. If Marianne's father calls and says he needs 15 pounds of potting soil, how many additional bags should she buy? Use the drop downs to put the correct number into the box to complete the statement.

Answer 1

Additional bags required = 4

Explanation:

Marianne buys number of bags of potting soil = 16

Each bag weighs =
`(3)/(4)` pounds

Total weight of 16 soil bags =
`16* (3)/(4)=12` 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 =
`\frac{\text{Weight of soil required}}{\text{Soil in each bag}}`

=
`(3)/((3)/(4))`

=
`3* (4)/(3)`

= 4 bags

Additional bags required by Marianne= 4
