Dmitry [639]

Step-by-step explanation:

Let the size of their father's land be x.

The first born received x/4

The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8

The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8

3x/8 = 3hectares

3x = 24

x = 8.

. : The initial size of the parcel land was 8 hectares.

Answer:

The cost per adult is $16.

Step-by-step explanation:

Given that:

Total number of children = 20+22 = 42 children

Total number of adults = 2 + 5 = 7 adults

Total cost for both groups = $490

Cost per child = $9.00

Cost of children ticket = 9.00*42 = $378

Cost of adult tickets = 490-378 = $112

This is the cost for 7 adult tickets.

Cost per ticket = $\frac{112}{7}$ = $16

Hence,

The cost per adult is $16.
