Question

If 4 tickets to a show cost $17.60, what is the cost of 7 such tickets.

Answer 1

30.80

Explanation:

We can use a ratio to solve

4 tickets 7 tickets

------------------- = ----------------

17.60 dollars x dollars

Using cross products

4x = 17.60 * 7

4x =123.2

Divide each side by 4

4x/4 = 123.2/4

x=30.8
