Answer:

32-40

Step-by-step explanation:

Since it does not give us any specifications as to the exact numbers, we can assume that the amount of adults ranges from 32 to 40, as these are the only numbers that are whole when divided. Obviously, we can't have 24.3333 of a person, so we have our range of answers.

Use simultaneous equation for this problem

y= number of adults

x = number of children

3y + 2x = 160

y + x = 60

then we double the second equation

3y + 2x = 160

2y + 2x = 120

we cancel x by elimination

3y - 2y = 160 - 120

y = 40
