7. last year, kimberly sold 95 boxes of cookies. This year, she wants to sell 20% more boxes than she sold last year. How many boxes will she have to sell this year to reach her goal?
+8581 1. what is 40% of 75
75 x 40 / 100
3000 / 100
30
3. 100%/x%=90/30
(100/x)*x=(90/30)*x - we multiply both sides of the equation by x
100=3*x - we divide both sides of the equation by (3) to get x
100/3=x
33.3333333333=x
x=33.3333333333
I'll let Rar do the rest!! <3
+5265 1. 40% of 75 is 30
75*.4=30
2. 30 is 33% of 90
90*.333...=30
3. 55 is 20% of 275
55/.2 = 275
4. She will have to sell 114 boxes because 95*.2=19
95+19=114.
