Question
Mavis bought some meat at the butcher shop. She picked up 3 lb 5 oz grilling steak, 2 lb 2oz of T-bone steak, and a 5 lb 11 oz sirloin roast. The cost was $3.21/lb. What was Mavis's total bill? (Recall: there is 16oz in 1 lb)
Solution
Step 1: Convert all the weights to the same unit. In this case, we'll convert everything to pounds.
- The grilling steak is already 3 lb 5 oz. To convert the ounces to pounds, divide by 16 (since there are 16 ounces in a pound). So, 5 oz = 5/16 lb = 0.3125 lb. So, the grilling steak is 3.3125 lb.
- The T-bone steak is 2 lb 2 oz. Converting the ounces to pounds gives 2/16 lb = 0.125 lb. So, the T-bone steak is 2.125 lb.
- The sirloin roast is 5 lb 11 oz. Converting the ounces to pounds gives 11/16 lb = 0.6875 lb. So, the sirloin roast is 5.6875 lb.
Step 2: Add up the total weight of the meat.
- Total weight = weight of grilling steak + weight of T-bone steak + weight of sirloin roast
- Total weight = 3.3125 lb + 2.125 lb + 5.6875 lb = 11.125 lb
Step 3: Multiply the total weight by the cost per pound to find the total cost.
- Total cost = total weight * cost per pound
- Total cost = 11.125 lb * 35.71
So, Mavis's total bill was $35.71.
