If you would like to find the inequality to determine the number of full-time employees Tom must schedule, you can calculate this using the following steps:
n ... the number of full-time employees
260 <= 20 + n * 40 260 - 20 <= n * 40 240 <= n * 40 n >= 240/40 n >= 6 full-time employees
The correct result would be at least 6 full-time employees.
Well a percentage is basically a decimal. If we take the 20 and times it by 5,we can get a 100th of a decimal, 15/100= 0.15. Now we just change it to a percentage! 15%
