PART A: One of Maria and Josie’s early tasks is printing and laminating signs to hang at local businesses around town. Working alone, Maria could print and laminate the signs in 4 hours. Josie, however, has better laminating equipment, so she could get the job done by herself in 2 hours. If each works for the same amount of time, how long will it take them working together to print and laminate the signs?

Start by filling in the table with the missing values or expressions. Note that rate of work is a unit rate that describes the amount of the job completed in one hour.

Rate of Work Time Worked Part of Task Completed
Maria x 4 x/4
Josie x 2 x/2

Part B Use the table in part A to create an equation. Then, solve it to find out how long will it take for Maria and Josie to complete the job together.
NOTE: I think I have Part A correct, and I need help with Part B
