Sandy has several pitchers to hold lemonade for the school bake sale. two pitchers can hold 64 ounces each, and four pitchers can hold 48 ounces each. how many total ounces can Sandy's pitchers hold?

The answer to this question would be:320 ounces

In this case, sandy has two kinds of a pitcher with different volume. To find the total volume of the pitcher, you need to multiply the pitcher count with the pitcher volume separately. The equation would be:

Total volume = pitchercount1 * pitchervolume1 + pitchercount2 * pitchervolume2

Total volume = 2 * 64 ounces + 4 * 48 ounces = 128+192 = 320 ounces
