ken went to a county fair and spent $5 admission, $6.50 on games, and $7.21 on food if he had $30 before he went to the fair, how much money does he have left

Ken has $11.29 left.

Step-by-step explanation:

To solve, all we need to do is add all the expenses together and subtract them from the total amount of cash he has, or $30.

The expenses are admission, games, and food.

5+6.50+7.21 = $18.71

Now subtract $18.71 from $30.

30-18.71=$11.29.

Ken has $11.29 or Eleven dollars and twenty-nine cents.

Is it 11.29

Step-by-step explanation:

Add 5+6.50+7.21 then you get 18.71 then subtract that from 30
