NEXT QUESTION
To solve this problem, we can use algebra.
Let's call Kelly's regular pay per hour "x".
According to the problem, Kelly makes $10 more per hour when working overtime. So, when working overtime, she earns x + 10 dollars per hour.
Yesterday, Kelly worked 8 regular hours and 4 overtime hours, for a total of 12 hours. We know that she earned $160 in total. We can set up an equation:
8x + 4(x + 10) = 160
Simplifying and solving for x, we get:
8x + 4x + 40 = 160
12x = 120
x = 10
Therefore, Kelly's regular pay per hour is $10.
Answer: $10 per hour.
