A car dealer sold x used cars and y new cars during May. If the number of used cars sold was 10 greater than the number of new cars sold. Which of the following expresses this relationship ? Choose the correct choice from the following choices:  A) x > 10y  B) x > y + 10  C) x > y – 10  D) x = y + 10  E) x = y – 10
Given: x used cars and y new cars   Number of used cars (x) sold was 10 greater than the number of new cars (y) sold   So, x is 10 greater than y   To show their relative sizes let's write x LARGER than y to get: x and y   Our goal is to create an EQUATION. So, how do we make these two values EQUAL?   Well, we need to make the smaller value (y) bigger. 10 bigger to be exact.   So, we get x = y + 10   Answer: x = y + 10
