Answer:
a. 12 mice
b. 8 mice
c. (X + 2) mice
Step-by-step explanation:
Given that one mouse is required for each snake, this implies that a snake is accompanied by a mouse. But two extra mice are included, let the number of snake be represented by N and number of mice be represented by L.
Supply needed = N + L + 2
= 2N + 2 (∵ N = L)
So that:
Number of mice needed = N + 2
a. When the number of snake is 10, the number of mice needed would be:
Number of mice needed = 10 + 2
= 12
Number of mice needed is 12.
b. When the number of snake is 6, the number of mice needed would be:
Number of mice needed = 6 + 2
= 8
Number of mice needed is 8.
c. When the number of snake is X, the number of mice needed would be:
Number of mice needed = X + 2
