Question

three roommates Ava, Ben, and Cora went grocery shopping online. Ava spent three times as much Ben and half as much Cora. If together they spent a total of 50, how much did Cora spend?

Answer 1

Cora's spend will be = $ 16.66

Explanation:

Let y be the amount Ben spent

As Ava spent three times Ben will be 3y and half as much Cora(2y)

so the equation becomes

y + 2y + 3y = 50

6y = 50

y = 50/6

y = 8.33

So Cora's spend will be : 2y = 2(8.33) = 16.66 units currency

Note: if currency is in $

Then Cora's spend will be = $ 16.66
