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. *first image attached* 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. Question 3 Part A The registration period for the race is under way, and as the word is getting out, the number of participants registering is growing exponentially. The numbers from the first two days of registration are shown in the table. Opening Day of Registration 1 Day after Opening Day regist Participants Registered 15 21 Use the data in the table and the general form of an exponential growth equation, y = a(1 + r)x, to write an equation modeling the exponential growth of registrations, where x is the number of days since registration opened, a is the initial number of registrations, r is the rate of growth of registrations per day, and y is the total number of registrations. Type the correct answer in the box. Round your answer to the nearest whole number. If the current trend of registration continues, there will be approximately _ participants registered 10 days after registration opens.
