Fill in the blank to write a one variable, one-step equation for the following information: The theater sold 15 more adult tickets than child tickets. The total number of child tickets sold was 42.(1 point)
a[ ? ]15=42
a + 15 = 42
wrong
a = 42 + 15
nope
a - 15 = 42
not even close
Let's try again. The correct one-variable, one-step equation for this scenario is:
a = c + 15
Where:
a = number of adult tickets
c = number of child tickets
Since the theater sold 15 more adult tickets than child tickets.
