Answer 1

Answer:

$3. \tim33.30 {366 {363 \times \frac{?}{?} }^{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} }^{?} es \frac{?}{?} }^{2}$

Answer 2

Answer:

1 ) 5 days and 10 hours = 65 / 12 days

Now , number of working hours = ( 65 / 12 ) * 9 = 48.75 hours

Now , rate = 238.5 $ / 3 hours

Hence , Total money = ( 238.5 / 3 ) * 48.75 = 38756.25 $ = 38756 $ Approx .

2 ) Since , number of each notes is 5 , hence

P ( Getting a 1$ Note ) = 5 / 25 = 1 / 5 = 0.2

3 ) Money which I paid first = 1.9% of 3920$ = 74.48$

But , due to discount of 80% , actual price you paid is 80 % of 74.48$ = 59.584$ = 60 $ Approx.
