That’s easy. To turn 5/2 into 10/4 you multiply by 2. :D Hope this helps!
-28 because using PEMDAS you would do -5x8 which =-40 plus 12 is -28
Answer:
91 child tickets were sold
Step-by-step explanation:
Let c represent the number of child tickets sold. Then the number of adult tickets sold is (150-c) and the total revenue is ...
5.20c +8.70(150-c) = 986.50
-3.50c +1305 = 986.50 . . . . simplify
-3.50c = -318.50 . . . . . subtract 1305
c = -381.50/-3.50 = 91
The number of child tickets sold that day was 91.
