Question

Mr. Vontay wants to give all 7 students a shout-out every day before December break. There are 3 days before break. If he gives 7 shout-outs per day, how many shout-outs will he give in total before break? Use linear equation. Then, solve.

Answer 1

We have 7 shout-outs per day.

There are 3 days before break.

Let t be the days before break and S the number of shout-outs before break, we can write a linear relation:

`S=7\cdot t`

Then, if there are 3 days before break, then t = 3 and S will be:

`S=7\cdot3=21`

Answer: he will give a total of 21 shout-outs.
