Question

If you burn 10 calories for every minute you jog, how many calories would you burn if you jogged for 20 minutes?

Answer 1

See a solution process below:

Explanation:

We can write an expression for calories burned as:

`10" calories" xx m`

Where `m` is the number of minutes jogged.

If we substitute `20` for `m` and evaluate the expression we get:

`10" calories" xx 20 = 200" calories"`
