3. You need 175 portions of sugar snap peas, each weighing 4 ounces. How many 10 -pound cases of peas should you purchase?

To calculate the total weight of sugar snap peas needed, multiply the number of portions (175) by the weight per portion (4 ounces). This gives you 700 ounces. Since there are 16 ounces in a pound, convert 700 ounces to pounds by dividing by 16, which equals 43.75 pounds. Now, since each case contains 10 pounds, divide 43.75 pounds by 10 pounds per case. You should purchase around 4.375 cases of peas. Since you can't buy a fraction of a case, you'll need to round up, meaning you'd need to buy 5 cases to ensure you have enough! But remember, it’s always better to have a little extra for that spontaneous stir-fry!
