the amusement park has 400 employees. 72% of them are part time employees. how many employees work full tim

288

Step-by-step explanation:

There are 2 ways to solve this problem. First, to find a percentage of any number you can use multiplication. When multiplying percentages you have to convert them into decimals. Do this by moving the decimal point 2 spaces to the left. This makes 72% = 0.72. Then, multiply this decimal by the whole to get the desired part. 400*0.72=288. Thus, there are 288 full-time workers.

Additionally, you can break the problem up to solve it. If you break up 400 into 4 parts you get 100. It is easy to find percentages of 100. So, obviously, 72% of 100 is 72. Next, you can multiply 72 by 4 to get 72% of 400, instead of just 100. Since 72*4 is 288, it is clear this method produces the same answer.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
