Answer:
Rolex earns $9 per hour.
Explanation:
Let the number of dollars he earns each hour be x.
To create our equation we need to find the total number of dollars he earned before his deduction which is 40x.
Then we know that he got 74 dollars deducted from his total earnings leaving him with 286 which gives us an equation. 40x + 74 = 286
40x - 74 = 286 (Equation)
40x = 360 (Add 74 from both sides)
x = 9 (Divide both sides by 40)
