4. How many total hours does a grocery clerk work if he

works 3 hr 30 min in the morning and 2 hr 15 min in

the afternoon five days a week?

A 26 hr 15 min

B 28 hr 45 min

C 29 hr 30 min

D 30 hr

The answer is 27:25 but it's not on your letters

B. 28 hr 45 min

Step-by-step explanation:

To find the answer we can do the following:

3 + 2 = 5 (number of hrs per day)

5 * 5 = 25 (number of hrs for 5 days without the minutes added on)

30 + 15 = 45 (number of minutes per day separate from hrs)

45 * 5 = 225 (number of minutes separate from hrs for 5 days)

225 minutes = 3 hours and 45 minutes (can be found by dividing 60 from 225)

25 hrs + 3 hrs 45 min = 28 hr 45 min
