better check your math. even a glance shows that 400+400 > 600
Ms. Singh, this is a very simple if you turn sentences into equations.
a = adults tickets
s = students tickets
There were 62 fewer student tickets sold than adult tickets means:
s = a - 62
Since 688 is the sum of adults tickets sold and students tickets sold:
a + s = 688
Replace s = a - 62 in this equation.
a + a - 62 = 688
2 a - 62 = 688
Add 62 to both sides
2 a = 688 + 62
2 a = 750
Divide both sides by 2
a = 750 / 2
a = 375
375 adults tickets were sold.
a = adults tickets
s = students tickets
There were 62 fewer student tickets sold than adult tickets means:
s = a - 62
Since 688 is the sum of adults tickets sold and students tickets sold:
a + s = 688
Replace s = a - 62 in this equation.
a + a - 62 = 688
2 a - 62 = 688
Add 62 to both sides
2 a = 688 + 62
2 a = 750
Divide both sides by 2
a = 750 / 2
a = 375
375 adults tickets were sold.
