Teresa and a friend ate 5.8 bags of trail mix on a
hiking trip. Each bag of trail mix contained 3.2
ounces. What was the number of ounces of trail
mix the 2 girls ate?

18.56 Ounces

Step-by-step explanation:

They ate 5.8 bags and each trail mix contained 3.2 ounces.

(5.8x3.2=18.56)

The reason you multiply is because they ate multiple bags and each one is 3.2 so to find the total the easiest way you would multiply.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
