To find out how many cups of spaghetti sauce 4 jars contain, we first need to convert fluid ounces to cups. There are 8 fluid ounces in 1 cup.
So, for one jar that contains 26 fluid ounces, we can calculate the number of cups it contains by dividing 26 by 8:
26 fluid ounces ÷ 8 fluid ounces/cup = 3.25 cups
This means one jar contains 3.25 cups of spaghetti sauce. Now, to find out how much spaghetti sauce is in 4 jars, we multiply the number of cups in one jar by 4:
3.25 cups/jar × 4 jars = 13 cups
Therefore, 4 jars contain a total of 13 cups of spaghetti sauce.
