Answer :
Nancy worked 60 hours last month, earning her hourly wage of $8 and receiving $140 in tips on top of that.
First, we need to find out how much money Nancy earned from her hourly wage. We do this by subtracting the amount of money she earned from tips from her total earnings: $620 - $140 = $480.
Now, we need to divide this amount by Nancy's hourly wage to find out how many hours she worked: $480 / $8 = 60 hours.
This means that Nancy worked 60 hours last month, earning her hourly wage of $8 and receiving $140 in tips on top of that.
To explain this answer further, we can say that Nancy's total earnings from her job as a pizza delivery person consisted of two parts: her hourly wage and the tips she received from customers. The hourly wage is a fixed amount that she earns for each hour of work, regardless of how many pizzas she delivers or how much money she makes in tips. The tips, on the other hand, are a variable amount that depends on how much money Nancy makes from her customers. In this case, Nancy earned $140 in tips on top of her hourly wage of $8, bringing her total earnings to $620 for the month. By dividing her total earnings by her hourly wage, we can find out how many hours Nancy worked to earn that amount of money.
