"Change in" also means "difference between" This means you you subtract the initial value from the final value In your question initial value= -6, final value = 17. (Warning - look out for the sign (+ or -) of the numbers)

would it be b

OpenStudy (mrnood):

don't guess = write down your equation : final value - initial value =??

OpenStudy (anonymous):

from 8:00 4:00 the temp changed into 11 ya?

OpenStudy (mrnood):

suppose one day you owed someone $6, and the next day, you had paid them back AND had $17 in your pocket. How much more money would you have? (owing = MINUS $6, in your pocket = PLUS $17 )

OpenStudy (anonymous):

it would be 11...

OpenStudy (mrnood):

That is not correct If you start counting at -6 (MINUS 6) and count upwards till you reach 17, how many counts have you made?

OpenStudy (anonymous):

negitive - postive is negitive so its 11-?

OpenStudy (mrnood):

do just what I said please - start counting upwards..... -6, -5, -4...............................15,16,17 How many steps?

OpenStudy (anonymous):
