What is the TOTAL change over four weeks.
So if the same change occurred each week, what weekly change over four weeks would equal the total change.
How did you get 62???
I added 148 + 100 = 248/ 4= 62.... but i put that answer in.. its still incorrect ; /
The magnitude of the TOTAL CHANGE in price is \(\displaystyle 148 - 100 = 48.\)
Did the price increase or decrease? So what is the SIGN of the total change in price?
A decrease is correct so the sign is negative. (Subtraction is an operation. It is a little annoying that the same symbol is used to indicate the operation of subtraction and the negative sign of a number.)
Your problem was that you were thinking about what was the average price, but the problem asks you what was the average change in price. So now that you know what the total change in price was over four weeks, can you see what the average change in price was over the four weeks?
