Answer:

1.2195

Step-by-step explanation:

For each month, he is given (on avg) $100 (CAD).

If on avg he can spend $82 (USD) each month,

then the USD: CAD ratio is

100:82, meaning $1 (USD) is equivalent to $.82(CAD)

and the exchange rate is calculated by equating  1 = .82x

thus, x= 1/.82 = 1.2195

You can peel 48 potatoes in 10 minutes. How long will it take you to peel 100 potatoes?
dybincka [34]

Answer:

About 20.8 minutes

Step-by-step explanation:

TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.

48

__

10

That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).

100

___

 x

Take these two ratios and set them equal to each other.

\frac{48}{10} =\frac{100}{x}      Next you cross multiply (take 48 times x and 100 times 10).

48x=1000    Now divide by 48 and you have your answer.

About 20.8 minutes
