Answer:
$11.05
Explanation:
To increase 6.50 by 70%, we first have to find what 1% equals. We can do this by dividing 6.50 by 100.
6.50/100 = 0.065
1% of 6.50 is 0.065.
Now since the department store increased the price by 70%, we'll have to multiply 0.065 by 170% (6.5 = 100%)
0.065 x 170 = 11.05
The new price is $11.05.
