Answer:
96
Step-by-step explanation:
Let x represent the number of adult tickets sold. Then (182-x) is the number of child tickets sold. The total sales is then ...
... 6.60·(182 -x) +9.80·x = 1508.40
... 3.20x = 1508.40 -1201.20 . . . . . simplify, subtract 1201.20
... 307.20/3.20 = x = 96 . . . . . . . . divide by the coefficient of x

4×(-5)=-20
The answer is 38
