a. 44.70 us dollars
b. 73.06 us dollars
c. 136.87 us dollars
d. 140.41 us dollars

The amount that he has now in dollars is 44.70 US dollars

The question says that the amount of USD that Phelan had was 250.

If 1 Euro is 1.3687, we have to convert this  250$ to Euros so that he can use the money in Europe.

1 euro = 1.3687 USD

? = 250 USD

We cross multiply at this stage

1€ x 250$ = 1.3687$

We have to divide through by 1.3687

After converting the 250 dollars he has 182.66 Euros.

The question says that he spent 150 euros on this trip

180.66- 150 = 36.66 Euros.

We have to convert 36.66 Euros back to dollars.

= 36.66x1.3687

= 44.70 dollars

In conclusion the amount that he has now in dollars is 44.70 US dollars
