a baker made cakes, cookies, and buns, of the total number of baked products he made, 28% more cookies. The number of cakes was three times the number of buns. He made 270 cakes. He sold 40 buns and 120 cakes. how many cookies must he sell that The ratio of the number of buns left the number of cakes to the number of cookies left is 1 : 3 : 2. HELP PLEASEEE

40 cookies was sold

Step-by-step explanation:

Let x represent the number of cakes baked, y represent the number of cookie baked and z represent the number of buns baked.

He made 270 cakes. Therefore x = 270

28% of the total baked products where cookies, hence:

0.28(270 + y + z) = y

75.6 + 0.28z = 0.72y

0.72y - 0.28z = 75.6      (1)

The number of cakes was three times the number of buns. Hence:

x = 3z

3z = 270

z = 90

Put z = 90 in equation 1:

0.72y - 0.28(90) = 75.6

0.72y -25.2 = 75.6

y = 140

Therefore 270 cakes was baked, 140 cookies was baked and 90 buns was baked.

He sold 40 buns and 120 cakes, the number of buns and cakes left is 50 buns and 150 cakes. Let us assume that number of cookies left was a. Since the ratio of left buns to cakes to cookies is 1:3:2. Hence:

(1/6) * (50 + 150 + a) = 50

300 = 200 + a

a = 100

Therefore 100 cookies was left. The number of sold cookies = 140 - 100 = 40

or

2x+8
