An exchange rate is a number that describes how much of one currency you can trade for another currency. For example, if the U.S. exchange rate for Canadian currency is 1.2, it means that you could trade one U.S. dollar for $1.20 Canadian. When travelers talk about how expensive or cheap a certain country is, it’s often a reflection of the exchange rate. The Big Mac costs mentioned earlier? The average cost in the U.S. in July 2016 was $5.06. In Russia it was just $2.15, and in Norway the cost was almost $6.

- Ruff, Inc. makes dog food out of chicken and grain. Chicken has 10 grams of protein and 5 grams of fat per ounce, and grain has 2 grams of protein and 2 grams of fat per ounce. A bag of dog food must contain at least 222 grams of protein and at least 162 grams of fat. If chicken costs 11¢ per ounce and grain costs 1¢ per ounce, how many ounces of each should Ruff use in each bag of dog food to minimize cost? (If an answer does not exist, enter DNE.)arrow_forwardQ6. Consider a situation where cars entering an intersection could turn right, turn left, or go straight. An experiment consists of observing two vehicles moving through the intersection. (a) How many sample points are there in the sample space? List them. (b) Assuming that all sample points are equally likely, what is the probability that at least one car turns left? (c) Again assuming equally likely sample points, what is the probability that at most one vehicle turns right?arrow_forward3.
