Question

Your cell phone company has a reward club. For every three texts you send you get 20 points. You need 1800 point for a prize. How many texts do you need to send to get a prize

Answer 1

Answer: 270

Step-by-step explanation:

Given: For every three texts you send you get 20 points.

Let x be the number of text need to send to score 1800 points.

Also the number of points is directly proportional to the number of texts,

Therefore,

$\frac{3}{20}=\frac{x}{1800}\\\Rightarrow\ x=\frac{1800\times3}{20}\\\Rightarrow\ x=270$

Hence, we need to send 270 texts to get the prize.
