Question

A total of 316 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?

Answer 1

Adults: 79 tickets

Students: 237 tickets

Explanation:

a + b = 316 Eq. 1

b = 3a Eq. 2

a = adults

b = students

Replacing Eq. 2 in Eq. 1

a + 3a= 316

4a = 316

a = 316/4

a = 79

from the Eq. 2

b = 3a

b = 3*79

b = 237

Check:

from the Eq. 1

a + b = 316

79 + 237 = 316
