Question

Tommy has a pet monkey. Every day, his monkey eats 4 apples in the morning. The monkey also eats two bananas for every banana that Tommy eats.
Write an equation to describe this situation where x is the number of bananas Tommy eats and y is the total number of pieces of fruit the monkey eats.

Answer 1

So,

x represents the number of bananas Tommy eats and y is the total number of pieces of fruit the monkey eats.

Translate the the second and third sentences in the question into mathematical form.
y = 4 (apples) + 2x (the number of bananas Tommy eats)
y = 2x + 4
This is actually slope intercept form, and it can be graphed.
