Movement helped you

Explanation:

The initial amount of $3,700 when converted to British pounds at a rate of $1:£0.49 yielded:

$I = \ 3,700*0.49\frac{\pounds}{\ }\\I=\pounds 1,813$

If the remaining amount was ​£146, the total spend in dollars is given by:

$S=\frac{\pounds1,813- \pounds146}{0.49} \\S=\ 3,402.04$

The amount spent in England in U.S.​ dollars was $3,402.04.

If the exchange rate was still $1:£0.49, the amount received back would be:

$A_1 = \frac{146}{0.49}=\ 297.96$

At the new rate of $1:£0.45, the amount received is:

$A_2 = \frac{146}{0.45}=\ 324.44$

Therefore, the movement in the exchange rate helped you.
