Question

During the past few years Great Britian's pund has been worth between $1 and $2 in US currency. Suppose the rate of exchange is $1.50 for each pund.

a. What is the value in dollars for 5 punds?

b. WHat is the value in pounds for $25.50?

a. 5 x 1.50 = value for $5 in pounds

b. 25.50 x 1.50 = value for $25.50 in pounds

On What is the value in ounds of $25.50?
I know the correct answer is 17 punds.

When I do
25.50 X 1.50= I get 38.25 what I am I doing wrong.

I'm sorry, I read it too fast. Divide 25.50 by 1.50 to get pounds.
