Answer:

Cora spent $ 30

Step-by-step explanation:

1. This is the information given to us to answer the question correctly:

x = Amount of money Ben spent

3x = Amount of money Ava spent (Ava spent three times as much as Ben)

6x = Amount of money Cora spent (half as much as Cora)

2. If together they spent a total of 50, how much did Cora spend?

Let's solve for x, this way:

x + 3x + 6x = 50

10x = 50

x = 50/10

x = 5

In consequence,

Ben spent $ 5 (x)

Ava spent $ 15 (3x)

Cora spent $ 30 (6x)
