Peter receives a $30000 salary for working as an engineer. If Peter spends 20% of his salary on expenses each year, then how much money does Peter have to spend on expenses?Identify the part, percent, and whole. Then solve with the formula

Answers

If Peter spends 20% of his salary on expenses, and his salary is $30,000, then all we need to do is find 20% of 30,000.

We can do this by converting 20% to a fraction or decimal. We'll do fraction because I think it is easier to see.

20% = 20/100 = 2/10 = 1/5

So we need to find 1/5th of 30,000

1/5 x 30,000 = 30,000/5 = 6,000

Therefore, Peter has $6,000 to spend on expenses.
Peter has $6000 to spend on expenses. You have to multiply 30000 time .20(the decimal form of 20%).
