Answer:
30 cups of flour
Step-by-step explanation:
Number of days for which Caroline baked bread = 5
Types of bread baked each day = 3
Number of cups of flour used for each recipe of bread = 2
=> Number of cups of flour used for 3 types of bread each day = 3 * (number of cups used / recipe) = 3 * 2 = 6 cups
=> Number of cups of flour used for 5 days = 5 * (number of cups of flours used per day) = 5*6 = 30
So Caroline used 30 cups of flour over 5 days.
