2. Suppose a truck travels at \(55 \mathrm{mph}\). How many miles will the truck travel in \(8\) hours?
3. A recipe calls for \(3\) cups of milk for \(8\) servings. How many cups of milk are needed to make \(6\) servings?
4. At a local college, the cost per unit of instruction is \(\$24.00\). If a student plans to take \(27.5\) units during the next two semesters, how much will the student pay for tuition?
