Answer:
35,648
Explanation:
Given that
Points scored for sending three texts = 1515
Total points needed to win the prize = 18001800
We need to find
Text needed to be sent to win the prize = x= ?
As per given info
3 texts sent give points = 1515
1 text sent give points = 1515/3
1 text sent give points = 505
Now we can use the following formula to calculate the total number of texts that need to be sent to win 18001800
Total Number of texts = Total Points needed to win the prize/ Points scored by sending a text
x= 18001800/505
x = 35,647.12 texts
this can be approximated to 35,648 texts to win the prize
