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

If you would like to write an equation to describe the following situation, you can do this like this:

4 apples in the morning ... 4
x ... the number of bananas Tommy eats
2 bananas for every banana that Tommy eats ... 2 * x
y ... the total number of pieces of fruit the monkey eats

The equation would be as follows: y = 4 + 2 * x.
