Answer 1

Solution:
A.	Amount to be paid in dollar for 83 Mexican pesos	4.3575
Working Notes:
	Mexican pesos are selling for $0.0525 per unit
	Means
	1 Mexican peso = $0.0525 per unit                        in other word $0.0525 per Mexican peso
	We need buy 83 units means 83 Mexican pesos
	Amount to be paid in dollar for 83 Mexican pesos
	= No of unit x price per peso
	= 83 x $0.0525
	= $4.3575
	=4.3575
B.	Number pounds we can buy from $100	82.7267
Working Notes:
	British pounds are selling for $1.2088 per unit
	Means
	1 British pound = $1.2088 per unit                          in other word $1.2088 per British pound
	Using unitary method
	$1.2088 = 1 British pound
So	$1   = (1/1.2088) British pound
Hence	$100 = 100 x (1/1.2088) British pound
	$100 = 82.72667108 British pound
	$100 = 82.7267 British pound
	Number pounds we can buy from $100
	=82.7267 Pounds
