Question: Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan’s bird feeder feed weekly?
Answer with step-by-step thinking: The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan’s bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly.
So the answer is 21.


Question: To make pizza, together with other ingredients, Kimber needs 10 cups of water, 16 cups of flour, and 1/2 times as many teaspoons of salt as the number of cups of flour. Calculate the combined total number of cups of water, flour, and teaspoons of salt that she needs to make the pizza.
Answer with step-by-step thinking: To make the pizza, Kimber half as many teaspoons of salt as the number of cups of flour, meaning she needs 1 / 2 * 16 = 8 teaspoons of salt. The total number of cups of flour and teaspoons of salt she needs is 8 + 16 = 24. She also needs 10 cups of water, which means the total number of cups of water and flour and teaspoons of salt she needs is 24 + 10 = 34.
So the answer is 34.


Question: The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old.
Answer with step-by-step thinking:
If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3 * 40 = 120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120 + 40 = 160 years. The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40 / 4 = 10 years old. Together, the three bands have a total of 10 + 160 = 170 years of existence.
So the answer is 170.
