By the end of this exploration, you will have a clear understanding of how to find the sum of digits in such numbers, improving your performance on the SAT Math section.

Question: Finding the Sum of Digits in a Two-Digit Number

Question: In a two-digit number, the units digit is x, and the tens digit is (x + 3). What is the sum of the digits in the number?

Options:

A) 11x + 3

B) 2x + 3

C) 3 + x

D) 11x + 30

Explanation and Key Concepts: When dealing with two-digit numbers, you can represent them as 10 times the tens digit plus the units digit. In this problem, the tens digit is (x + 3), and the units digit is 'x.' The sum of the digits is found by adding the tens and units digits, which leads to the expression 11x + 30.
