First we need to find the rate of logging for employee A per year. To do this, the number of hours can be divided by the number of years to find out how many hours of travel they log per year.
120 ÷ 4 = 30. Employee A logs roughly 30 hours of travel per year.
To find a percentage increase of 20%, you need to multiply by 1.2. 30 x 1.2 = 36. Therefore, Employee B logs roughly 36 hours of travel per year.
To find out how many hours of travel Employee B logs after 1.5 years, we simply need to multiply 36 by 1.5, which equals 54.
To find out how many hours of travel Employee A logs after 1.5 years, we simply need to multiply 30 by 1.5, which equals 45.
Finally, we need to find out how many MORE hours Employee B logged after 1.5 years compared to Employee A. To do this, we simply need to do 54 - 45 = 9 hours.
Working = (((120/4) x 1.2) x 1.5) - (120/4 x 1.5) Answer = 9 hours.
These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
The first answer is 36 and the second is 80 because each pattern increases by one tile longer and wider so pattern 4 would be 4 by 4 so there would be 16 square tiles and 16 circular tiles and pattern 5 would have 25 square tiles and 20 circular tiles.
