This is the simplified expression.
Answer: Nya will pay $40.81 for the sweater.
Step-by-step explanation: First, take $55, and multiply it by 0.3 to get 30 percent of $55. This turns out to be $16.5. Next, you do $55 - $16.5 because the sweater is 30% off, and not 30% of the original rate. Now you multiply the difference of $55 - $16.5, so $38.5, and you multiply it by 0.06 to get $2.31. Last, add $38.5 and $2.31 to get $40.81.
We know that one Canadian dollar is $1.12 in U.S. dollars. We can multiply 250*1.12 to get $250 USD in Canadian dollars. This gives us 280. The answer is $280 Canadian dollars is equivalent to $250 U.S. dollars.
If this was shown as a fraction, you would have 1.12/1. Next, we know that there are $250 U.S. dollars. 1*250 is 250. 1.12*250 is $280.
