Question

Your cell phone company started a rewards club. For every three texts sent, you get 15 points. You need 1800 points for a prize. How many texts do you need to send to get that prize

Answer 1

360 texts

Explanation:

Given,

The points given for 3 texts = 15,

So, the points given for 1 text =
`(15)/(3)` = 5,

If x text are sent,

Then the number of points earned = x × points for 1 text

= 5x

According to the question,

5x = 1800

`\impilies x = (1800)/(5) = 360`

Hence, 360 texts needs to send to get 1800 points.
