To find out how many times as much the cost of each share of stock in Company A was in 2010 compared to 1960, we will use the formula:
[tex]\[ \text{Ratio} = \frac{\text{2010 Cost}}{\text{1960 Cost}} \][/tex]
For Company A:
- The cost in 1960 was [tex]$0.45.
- The cost in 2010 was $[/tex]6.75.
Substituting these values into the formula, we get:
[tex]\[ \text{Ratio for Company A} = \frac{6.75}{0.45} \][/tex]
By performing the division:
[tex]\[ \text{Ratio for Company A} = 15.0 \][/tex]
Therefore, the cost of each share of stock in Company A was [tex]\( \boxed{15.0} \)[/tex] times as much in 2010.
