Translation from word problems to mathematical expressions
Suppose y is the number mentioned in the problem.
Sometimes it's better to read the problem from end to beginning. Let's start by:
5y = 5 times a number.
Now we follow up with:
5y - 28 = 28 less than 5 times a number
Now we equate to 15:
15 = 5y - 28
Correct answer: B)
