Question

The number of pizza slices Gilbert ate is four more than three times the amount of candy bars he ate. He ate 10 slices of pizza. How many candy bars did he eat?

Answer 1

2

Explanation:

Consider this question using algebra.

Let the number of candy bars eaten =
`x`

We are told that Gilbert ate four more than three times the amount of candy bars he ate (pizza). This means that he ate three times the amount of candy bars, plus an extra four slices.

We can use these to form an expression, using our knowledge of
`x` being the number of candy bars eaten and 10 being the number of pizza slices he ate:

`3x+4=10`

Now, we solve for
`x` to find the number of candy bars he ate:

`3x+4=10\\3x=6\\x=2`

Therefore, he ate 2 candy bars.

Answer 2

3 x 10 + 4 = 34 so the answer would be he ate 34 candy bars
