What’s the equation?
Sphinxa [80]
If Whitney works 51 hours per week, then that would mean that we’d use the expression 51w because w, representing the weeks, would be multiplied by 51 to find the amount of hours worked in that week. However, since 15 of the hours were spent outside instead of in the office, we’d have to subtract that from the 51w. Therefore, the equation would be:

h= 51w - 15
