The Green Soles Nature Club uses liquid fertilizer when planting trees. The garden center gave them 42 gallons which was enough for 35 trees. How many
gallons do they need for the 10 trees they will plant next week?

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)
