Answer:
D. Quickgrow
Step-by-step explanation:
You have to find the unit rate first. 120 acres divided by 12 cup of seeds, you get 10 acres for 1 cup of seeds. For green grass you get 7.6 acers for 1 cup of seed. Since your trying to figure out which brand of seeds can cover up more acers, 10 is greater than 7.6. Therefore Quickgrow would cover up more land.
Sorry is my explanation is confusing.
The answers are B,C, and F because you have to set up proportions.
If the groups are all made up of 10 pennies and she added 5 groups, then
5 x 10 = 50
Which means she added 50 pennies to the jar and now has 150 pennies. :)
