Question

In 1819, the United States purchased Florida from Spain for

$5 X 106. The area of Florida is about 6.6 x 104 square miles.
Which key strokes on a calculator will give the cost the
United States paid for each square mile of Florida?

Answer 1

Like Eduard22sly said D). 5 EE 6 ÷ 6.6 EE 4 is correct.

plus i took the test 100% :)

Answer 2

Option D. 5 EE 6 ÷ 6.6 EE 4

Explanation:

Data obtained from the question include the following:

Area of land purchased = 6.6×10^4 square miles

Cost = $ 5×10^6

To determine the key strokes on a calculator which will give the cost the

United States paid for each square mile of Florida, let us calculate cost of 1 square mile.

This can be obtained as follow:

6.6×10^4 sq mile = $ 5×10^6

Therefore,

1 sq mile = $ 5×10^6 ÷ 6.6×10^4

In calculator, the key strokes will be:

5 EE 6 ÷ 6.6 EE 4
