A family of 3 goes to a fair. Tickets cost $5 each, but each person has a coupon. They pay $7 altogether.
How much money does each person save on buying
their ticket?

5x - 7 = 3

7 = 3(5 + x)

3x + 5 = -7

x + 7 = 3 x 5

$2.66

Step-by-step explanation:

Step 1: Multiply the $5 to the family of 3

That's what they would have paid if they did not have a coupon. Now they have a coupon and only pay $7.

Step 2: Subtract what they paid from the result

Now we have found how much they save altogether. To find how much they saved each;

Step 3: Divide the result found in step 2 by the family of 3

Each person saves approximately $2.66
