Question

Mineola High School sold 105 tickets on the first 3 days of ticket sales for the school play. They sold 30 tickets on the first day, 55 tickets on the second day and s number of tickets on the third day. Which equation can be used to find s, the number of tickets sold on the third day? A 105 = 30 + (55 - s)

B 105 = (s +55) - 30
C 105 = 55 - (30+ s)
D 105 = (30 + 55) + s​

Answer 1

The correct equation to find the number of tickets sold on the third day is D. 105 = (30 + 55) + s, representing the total sales after three days.

Step-by-step explanation:

The equation to find s, the number of tickets sold on the third day, when Mineola High School sold 105 tickets on the first three days, is given by the total sales minus the sales from the first two days. If they sold 30 tickets on the first day and 55 on the second day, then the equation representing the third day sales is:

D. 105 = (30 + 55) + s

This equation adds up the tickets sold across all three days, setting it equal to the known total (105), which can then be solved for s.
