A car dealership decreased the price of a certain car by 4%. The original price was
serg [7]
%change=100(final-initial)/initial, 

%change=100(New price-Original price)/Original price

(Original price*%change)/100=New price-Original price

New Price=(Original price*%change+100*Original price)/100

New Price=Original price(100+%change)/100

Since %change is -4%...

New Price=0.96(Original price)

...

Since original price is $45400

New Price=0.96(45400)

New Price=$43584

Adam exchanged British pounds for Swiss franc He changed £400 into 592 francs What was the exchange rate of British pounds to Sw
OLEGan [10]

Answer: 1 : 1.48

Step-by-step explanation:

Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.

The exchange rate can be gotten using direct proportion:

400 : 592

1       : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

Exchange rate is:

= 1 : 1.48
