Question

Mateo is thinking of a whole number .If he multiplies his number by 3, the answer is less than 30 .If he multiplies his number by 6, the answer is more that 40.There is more than one number that Mateo could be thinking off.

What is the sum of all of the numbers Mateo could be thinking of?

Answer 1

If Mateo's number multiplied by 3 is less than 30, then the largest number that he could be thinking of is 9 (since 9 x 3 = 27). If Mateo's number multiplied by 6 is more than 40, then the smallest number he could be thinking of is 7 (since 7 x 6 = 42).

Therefore, the possible numbers that Mateo could be thinking of are 7, 8, and 9. The sum of these numbers is:

7 + 8 + 9 = 24

So, the sum of all the numbers that Mateo could be thinking of is 24.

I hope this helped!
