We know for our problem that Rachel makes $10 per hour. Since
represent the number of hours that she works, 
will be the total amount that she will make for working hours. We also know that she sells bracelets for $5 each. Since 
represents the number of of bracelets that she sells, 
will be her total revenue for selling bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of and must be equal or greater than 200:

To find the length of a line given two points, we are going to use the distance formula, which is defined below:
( and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
- Substitute values into formula
- Combine like terms and then simplify
to 0
- Compute
- Compute
The length of DC is 3.
