Tickets

One thousand two hundred sixty tickets sold. On the first day, 80% was sold on the second day was sold. How many tickets were sold first, and how much the next day?

Correct answer:

a =  560
b =  700

Step-by-step explanation:


a+b = 1260
a = 0.80 · b

a+b = 1260
a-0.8b = 0

Row 2 - Row 1 → Row 2
a+b = 1260
-1.8b = -1260


b = -1260/-1.8 = 700
a = 1260-b = 1260-700 = 560

a = 560
b = 700
