One of the team is from greece and wants to change his wages from pounds sterling to euros. the exchange rate is €1 = £0.72.
if he earns £135, how many euros will he get?



the arena’s stage is 8 metres long. the left hand and right hand sides of the stage will be taken up by large speakers with a 130 cm base each.
how many metres of the stage will be left free for the band?

Part A: 

To determine the amount of money in Euros that the team will get, we use the original amount given, the proper dimensional analysis and the conversion factor. For this item,
    (£135) x (€1 / £0.72) = €187.5

ANSWER:  €187.5

Part B:

Convert first the given length of the arena's stage in centimeters by using the conversion factor, 1 m = 100 cm

    (8 meters) x (100 cm/1 m) = 800 cm

Since, both sides will be occupied by 130-cm speaker,

    remaining length = 800 - 2(130 cm)
    remaining length = 540 cm

ANSWER: 540 cm or 5.4 m
