Answer:
The sweaters cost $35 each.
Step-by-step explanation:
The skirt was $20, so you would subtract 20 from 160. that equals 140. Then you would divide 140 by 4. that would equal 35. So the answer is $35.
Do the area of the circle as a whole minus (72/360 x radius^2) and then minus the other grey area.
What you’re doing is breaking it down into its parts and writing it into an equation that way long hand.
3 + .4 + .00 + .005
The answer to the second one is 243/2 but I'm not 100% positive
