Mr. Johnson is organizing the school Christmas play and needs 50 volunteers to help with decorating the auditorium. 5 students from each of the school’s 6 math classes have volunteered to help. 13 teachers have also volunteered to help. How many more volunteers will Mr. Johnson need? Give me reasons, before answering the question

Since 5 students from each of the 6 math classes have volunteered, there are 5 * 6 = 30 total student volunteers. In addition to the 30 student volunteers, 13 teachers have also volunteered so there are 30 + 13 = 43 total volunteers. Mr. Johnson needs 50 volunteers and currently has 43 volunteers, so he needs 50 - 43 = 7 more volunteers. So the final answer is 7.
