To find the number when 45 is 30% of it, you can set up the equation: \( 0.3 \times X = 45 \). To solve for \( X \), simply divide both sides by 0.3. So, \( X = \frac{45}{0.3} \). This gives you \( X = 150 \). Voila! The number is 150! Interestingly, this method of using percentages is incredibly useful in various real-life contexts, such as calculating discounts during shopping, determining tax rates, or figuring out tips at restaurants. Being able to quickly convert percentages into numerical values can save you money and time!

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? Brand B, z represent the number of cases of Brand C, and \( w \) represent be the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat.
