Since the dvd is $7.55 "Less" than the CD you should add.
$14.95+$7.55=$22.5
That's your answer to how much the dvd is.
If you have to subtract it
Write it like this $22.5-$7.55=$14.95
The answer is 15:25 but when simplified it is 3:5
Hey there!
The correct answer is the last option, 140.
The shape shown is a triangle, and a triangle has a total measure of 180° . . .
If we add 30 and 10 then subtract that from 180, you will get your answer.
30 + 10 = 40
180 - 40 = 140
