6n = 180 6n /6 = 180 /6 n = 30 Sharon sold 30 binders. ||
 * **Example 1** || **Solution** ||
 * Sharon works in a sports card shop. Card binders cost $6.00 each. One week, she sold $180.00 worth of binders. How many did she sell? || Let n represent the number of binders sold. Write and solve an equation.

Then, Rick's hours are x - 5. The equation is: x - 5 = 11 x - 5 + 5 = 11 + 5 x = 16 Chuck worked 16 hours. ||
 * ** Example 2 ** || ** Solution ** ||
 * Rick and Chuck also work at the card shop. Rick worked 5 hours less than Chuck. Rick worked 11 hours. How many hours did Chuck work? || Let Chuck's hours be x.
