Explanation

0.25(x) + 0.40(100−x) =28

0.25 x + 40 − 0.40 x =28

0.25 x − 0.40 x =28−40

− 0.15 x = −12

x = 0.15/ 12  =80

c) Vanilla = 135

Step-by-step explanation:

Given,

There are three flavors of ice cream ( Mango , Banana , Vanilla).

There were 900 cups sold on one day with the ratio of the cups sold being 5 : 12 : 3 respectively, We need to find the number of cups sold in each flavor.

The total ratio of cups = 5 + 12 + 3 = 20

The number of cups sold in Mango flavor = 5 * 900 / 20 = 225

The number of cups sold in Banana flavor = 12 * 900 / 20 = 540

The number of cups sold in Vanilla Flavor = 3 * 900 / 20 = 135
