This question is not even trying to test your arithmetic. It's just testing to see whether you know how to read numbers in words properly.
When you read numbers in words, the only time you ever say "and" is for a decimal point. There are no decimals in this question, so the "and" is not a part of any numbers.
The question gives you two numbers. The word "and" is the marker that's
BETWEEN them. The two numbers are 1,300 and 950 .
The first thing the question wants you to do is write the numerical expression for all the words. That's (1300 - 950) / 4 .
The next thing you're supposed to do is"evaluate the expression" ... find out what number it all boils down to. I don't think you'll have any trouble with that now.
