Aschool group is plant a new city garden. today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden. how much more potting soil will they need to finish tomorrow?

pounds.  

Step-by-step explanation:

Let x be the total amount of potting soil needed to complete the planting in new garden.    

We are told that a school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden. This means 2/5 of x equals to 12 1/2.

To find the amount of soil needed for the next of planting we will subtract the amount of potting soil used on the first day from amount of total potting soil .

Therefore, the group will need pounds of potting soil to finish their work.            

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
