We have to find out the number of trees planted per unit rate of time.
Kyla can plant 300 trees in 1 hour, so she can plant 300 trees in 3600 seconds. This implies that she can plant
trees per second.
On the other hand, Mia can plant 1 tree in 13 seconds, so she can plant
trees per second.
Working together they can plant
trees per second, i.e. it takes them 156/25 seconds to plant a tree.
We conclude that they plany 100 trees in
seconds

Answer:
Rose will have 2.32$ leftover. She is able to get 3 more bouncy balls.
Step-by-step explanation:
To get the cost of 12 bouncy balls - 12*0.64 = 7.68$
To get the leftover amount - 10.00-7.68 = 2.32$
To find how many more bouncy balls she could get - 2.32/0.64 = 3.625 which is then 3 bouncy balls because you cannot buy .625 of a bouncy ball.
