To the second part, as you are doing this one, keep in mind that per means to divide and 1.5%=0.015.

Set up a proportion for your exchange rate:

1.5 francs = ___ Francs

_______ __________

1 dollar 600 dollars

Cross multiply and you get 1.5 x 600 / 1 = 900 Francs

The 1.5% fee would be 900 francs x .015 = 13.50 francs

1.5 francs = 13.50 francs

_______ ________

$10 $_____

13.50 x 10 / 1.5 = $90 for the exchange fee. So, no the $10 is not nearly enough.

The $10 would convert to 15 Francs, so you would have:

900 Francs + 15 Francs – 13.50 Francs = 901.50 Francs

After the trip, you would convert your 321 back to dollars using the same proportion:

1.5 francs = 321 francs

_______ ________

1 dollar ___ dollars

321 x 1 / 1.5 = $214.00

1 mile = 5280 ft = 63360 inches

By ratio and proportion:

1mi/63360 in = 8mi/x

x = 63360(8)

x = 506,880 inches

2. a. Let x be the exchange fee which is equal to 1.5% of $600.

By ratio and proportion:

1.5/100=x/600

100x = 1.5(600)

x=900/100

x = 9

1.5% of $600 is $9, therefore, you still have excess of $1 out of the $10 for the exchange fee.

10-9=1.

b. Le x be the francs equivalent of $600.

$1 = 1.5 francs

$600 = x

By ration and proportion:

1/1.5 = 600/x

x=600(1.5)

x = 900 francs

c. Let x be the dollar equivalent of 321 francs

1.5 francs = 1 dollar

321 francs=x

By ration and proportion:

1.5/1 = 321/x

x=321/1.5

x = 214 dollars

GOOD LUCK!

1.5 franc = $1

1.5% = exchange fee

$600 = amount to be exchanged

a.) $600 – .015(600) = $600 – $9, so yes, $10 is enough to cover the exchange fee

b.) $600 X 1.5f = 900f (exchange fee comes from extra $10 so is not part of this equation)

c.) 321f/x = 1.5f/$1 = 321/1.5 = $214

b.) SF900.00 -SF13.50 (Exchange Fee) = 886.50 Swiss Francs.

c.) $214.00.

That was too easy.

5,280ft x 8 miles = 42,240 ft = 8 miles

42,240 ft x 12in =

506,880 inches = 8 mile

2nd question- i don’t get it
