In general, when you state "the difference between a point A and a point B" meaning that you have to take the final value at the point B subtract the initial value at the point A"
<span>For example: Find the difference in distance between a point A =2 m and a point B = 5 m? </span>
<span>In this case: </span>
<span>In general: The difference in distance = 5 m - 2 m = 3 m </span>
<span>You can also write it as: </span>
<span>The difference in distance = 2 m - 5 m = -3 m </span>
<span>Since the distance between 2 points CAN'T be a negative value, you've to take the absolute value of -3 m to get the positive answer of 3 m. </span>
<span>This based on a scalar quantity. </span>
<span>Unless you're working on a Vector problem in Physics. In this case, you must take the final point subtract the initial point since the motion not only describes the magnitude but also describes the direction of the motion as well. </span>
<span>Again, in this case, you can have the magnitude is always a POSITIVE number and the direction can be either POSITIVE or NEGATIVE depends on the direction that you chose as a positive. </span>
<span>Back to your question. "the difference between 15 and the product of 5 and y" </span>
<span>I would write this statement as 5y - 15 </span>
Think of it like fractions. If the total of Emily's class is 40% or $580, put it into fractions. You know the total of everything is 100% and her class raised 40%. So write it as a fraction, 40 over 100. Then, write another fraction with 580 on the top, equivalent to 40%. Then you must cross multiply and divide. So multiply 100 times 580 and divide the product by 40 to get the equivalent of 100%. Therefore, the answer would be $1450. Make sense? Maybe this picture will help.
