Final answer:
To estimate the cost of each soccer ball, divide the total cost by the number of soccer balls. The exact cost can be found by the same calculation. The estimate and exact cost are both $14.40.
Step-by-step explanation:
To estimate the cost of each soccer ball, we can divide the total cost ($216) by the number of soccer balls (15). This gives us an estimate of $14.40 per soccer ball.
The equation to show this is: Cost per soccer ball = Total cost / Number of soccer balls. Substituting the values, we get the Cost per soccer ball = $216 / 15 = $14.40.
To find the exact cost of each soccer ball, we can divide the total cost of $216 by the number of soccer balls, which is 15. This gives us the exact cost of $14.40 per soccer ball.
Comparing our estimate and the exact cost, we see that they are the same, which means our estimate was reasonable. Both the estimate and the exact cost of each soccer ball are $14.40.
