Apair of $195 boots are discounted 40% if the boots are reduced in price by an additional 66 2/3% what will the discount price be?

First, find the 40% discount.
40% of 195 is 78
195 x 0.40 = 78
Subtract that from 195
195 - 78 = 117
Now, find 66 2/3% of 117, since it is an additional reduction after the original discount.
2/3 = 0.667, so 66 2/3% is 66.667%
117 x 0.66667 = 78.00039
And subtract that from 117
117 - 78.00039 = 38.99961, which in dollars would be $38.99. (hundredths, etc. of a cent are usually just dropped; no rounding involved.)
The discount price would then be $38.99

First, we find 40% of 195 and subtract it:

0.40 * 195 = 78

195 - 78 = 117

Now let's find 66 2/3% of this and subtract it.

2/3 * 117 = 78

117 - 78 = 39

So the discount price is $39
