there are 216 trees to be planned in a park. there are 54 people who will plant the trees. Each person will plant the same number of trees how many trees will each person plant
Method 1:
Suppose each person plants N trees, then the total number of trees planted
is:
Nx54 = 216.
Divide both sides of this equation by 54 gives:
N = 216/54 = 4.
Method 2:
Suppose they plant 1 tree each, then the total is 54 trees, but this is less
than the 216 we are told were planted.
So now guess they plant 2, then the total planted is 108, still not enogh.
Try 3, total is now 162 getting closser.
Try 4, total is now 216, which is the required total.
Method 3:
The round the numbers, then the total number of trees is 200, and planters
is 50. 50 planters would have to plant 4 trees each to plant a total of 200.
Now check that if 54 planters plant 4 trees each then the total is 216.

ben wants to buy a guitar the regular price of the guitar is 329.99. the sale price of the guitar is 25% off the regular price. what is the sale price of the guitar?
ben must pay 7.25% sales tax in addition to the sale price of the guitar. what is the total amount ben must pay for the guitar
Hello,
original price is 100% -------------> $329,99
sale price is 75% -----------------> $329.99 * 0.75 = $247.49
tax is 7.25% from the sale price ---> $247.49 * 0.0725 = $17.94
Add sale price and tax to get the total amount: $265.43
