D. A number increased by 20 is 30 more than the number increased by

Answer 1

The expression 20s can be represented by the situation in option C, which translates into the equation 20s = 14s + 30, resulting in the number 5 when solved.

Step-by-step explanation:

The situation that can be represented by the expression 20s is option C, which states 'Twenty times a number is equal to 14 times the number increased by 30.'

This is translated mathematically into the equation 20s = 14s + 30, where s represents the number in question. To find the value of s, you would subtract 14s from both sides of the equation, yielding 6s = 30, and then divide both sides by 6 to get s = 5. Therefore, the number that makes the equation true is 5.
