Mario's locker number is between 80 and 99. The sum of the digits is 13. The tens digit is 3 more than the ones digit. What is Mario's locker number?
81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 93, 94, 95, 96, 97, 98
I see two numbers above in which the digits add up to 13.
85
Idk lol
To find Mario's locker number, we can use the given information to systematically narrow down the possibilities.
1. The locker number is between 80 and 99.
Starting with the given range, we have: 80, 81, 82, ..., 98, 99.
2. The sum of the digits is 13.
Let's examine each possibility and find the numbers that satisfy this condition:
- For 80, the sum of its digits is 8 + 0 = 8 (not 13).
- For 81, the sum of its digits is 8 + 1 = 9 (not 13).
- For 82, the sum of its digits is 8 + 2 = 10 (not 13).
(continue this process for each number until 99)
The possible numbers that have a sum of digits equal to 13 are: 85, 94.
3. The tens digit is 3 more than the ones digit.
Now let's check which number satisfies this condition:
- For 85, the tens digit (8) is not 3 more than the ones digit (5).
- For 94, the tens digit (9) is 3 more than the ones digit (4).
So, Mario's locker number is 94.
