Number of candy bars sold by girls altogether is 91
<h3><u>Solution:</u></h3>
Given that The ratio of candy bars sold by Anna, Elisa and Tiara are 2 to 4 to 7
So ratio of candy bars sold by Anna, Elisa and Tiara = 2 : 4 : 7
Let the candy bars sold by Anna be 2a
Let the candy bars sold by Elisa be 4a
Let the candy bars sold by Tiara be 7a
Given that Elisa has sold 28 candy bars
Number of candy bars sold by Elisa = 28
4a = 28
a = 7
So we have found "a" as 7
Thus we get,
candy bars sold by Anna = 2a = 2(7) = 14
candy bars sold by Elisa = 4a = 4(7) = 28
candy bars sold by Tiara = 7a = 7(7) = 49
We have to find the number of candy bars sold by girls altogether
<em>number of candy bars sold by girls altogether = candy bars sold by Anna + candy bars sold by Elisa + candy bars sold by Tiara </em>
number of candy bars sold by girls altogether = 14 + 28 + 49 = 91
So altogether girls sold 91 candies
