chris janet how much dresses
x + (x+5) = 31
use the above formula
x+x = 31-5
2x = 26
x=13
so chris needs 13
and add x into x+5
janet needs to make 18
To find out how many dresses Janet has to make, we can start by setting up an equation based on the given information. Let's assume Chris has to make x dresses.
According to the problem, Janet has to sew 5 more dresses than Chris. So, Janet's number of dresses would be x + 5.
Together, they have to make 31 dresses in a month. Therefore, the sum of their dresses should be equal to 31.
x + (x + 5) = 31
By simplifying the equation, we have:
2x + 5 = 31
Now, we can isolate x by subtracting 5 from both sides of the equation:
2x = 31 - 5
2x = 26
Finally, divide both sides of the equation by 2 to solve for x:
x = 26 / 2
x = 13
Chris has to make 13 dresses in a month. Since Janet has to sew 5 more dresses than Chris, she would have to make 13 + 5 = 18 dresses.
Therefore, Janet has to make 18 dresses.
