We can start by finding the total number of calculators ordered. Since there are twelve people and half of them ordered a $9.95 calculator, that means 6 people ordered that calculator. Let's assume the other 6 people split evenly between the cheapest and most expensive calculator options. That means 3 people ordered the $5.95 calculator and 3 people ordered the $12.95 calculator.
Now we can find the total amount spent on calculators by multiplying the number of each calculator by its respective price and adding them together:
6 x $9.95 = $59.70 (for the 6 people who ordered that calculator)
3 x $5.95 = $17.85 (for the 3 people who ordered the cheapest calculator)
3 x $12.95 = $38.85 (for the 3 people who ordered the most expensive calculator)
Adding those three amounts together, we get:
$59.70 + $17.85 + $38.85 = $116.40
So the best estimate for the amount spent on calculators is $116.40. None of the given options match exactly, but $125 is the closest. Thus, the answer is:
$125
