It can be deduced that the price of the trick cameras will be $5 and the price of the snakes will be $6.25.
Based on the information given, the equation to solve the question will be:
3x + 4y = 40 ...... i
7x + 8y = 85 ...... ii
Multiply equation i by 7
Multiply equation ii by 3
21x + 28y = 280
21x + 24y = 255
Subtract the equations
4y = 25
y = 25/4 = 6.25
Since 3x + 4y = 40
3x + 4(6.25) = 40
3x + 25 = 40
3x = 40 - 25.
3x = 15
x = 15/3 = 5
Therefore, the price of the trick cameras will be $5 and the price of the snakes will be $6.25.

Natural numbers:
Natural numbers are those numbers starting from 1 , 2 , 3 , 4 ,......... and so on.
Also it is denoted by 'N'.
Zero does not include a natural number.
Therefore the set of natural numbers less than 6 is 1 , 2 , 3 , 4 , and 5.
Here in the question it is given that
P is the set of natural numbers
less than 6.
∴ P = { 1 , 2 , 3 , 4 , 5 }
