Answer:
- 156 children
- 145 adults
Step-by-step explanation:
Let number of adults be a and children be c
Then we have equations
- a + c = 301
- 4a + 1.5c = 814
From the first equation we get a = 301 - c, we substitute a in the second equation:
- 4(301 -c) + 1.5c = 814
- 1204 - 4c + 1.5c = 814
- 2.5c = 1204 - 814
- 2.5c = 390
- c = 390/2.5
- c = 156
Then finding the value of a:
- a = 301 - 156 = 145
