Isaiah And Cooper work at a dry cleaner Ironing shirts.isaiah can iron 25 shirts per hour, and Cooper can iron 30 shirts per hou
r. Cooper worked twice as many hours as Isaiah And they ironed 340 shirts between them. Write a system of equations that could be used to determine the number of hours Isaiah worked and the number of hours cooper worked . Define the variables that you use to write the system
2 answers:
<u>Define Variables:</u>
Let x = the number of hours Isaiah worked
Let y = the number of hours Cooper worked
Isaiah can iron 25 shirts each hour, so in x hours he can iron 25x shirts. Cooper can iron 30 shirts each hour, so in y hours he can iron 30y shirts. The total number of shirts ironed 25x+30y equals 340
Since Cooper worked twice as many hours as Isaiah, Cooper worked <em>more </em>hours, so if we multiply 2 by the number of hours Isaiah worked, we will get the number of hours Cooper worked, meaning y equals 2x.
<u>System of Equations:</u>
25x + 30y = 340
y = 2x

<u>Step 1: Determine the median</u>
The median of a set is the middle of the set. In this instance, we have 6 numbers so we don't have a number directly in the set representing the median. Instead, we need to find the average or middle between the 3rd and 4th number. So we take 2.7 and 2.8, add them together to get 5.5 and then we divide by 2 to get 2.75 which is our median.
