Final answer:
Keisha needs to buy 2268 grams of cheese to make 5 batches of enchiladas, as each batch requires 16 ounces and 1 ounce is equivalent to 28.35 grams.
Step-by-step explanation:
Keisha wants to make 5 batches of enchiladas, and each batch requires 16 ounces of cheese. To convert ounces to grams, we use the conversion factor of 1 ounce being equivalent to approximately 28.35 grams. Therefore, Keisha needs to convert the total ounces of cheese needed for 5 batches into grams.
First, let's find out the total ounces of cheese she needs for the 5 batches:
- Multiply the amount of cheese per batch by the number of batches: 16 oz/batch × 5 batches = 80 ounces of cheese.
- Convert the total ounces to grams: 80 oz × 28.35 g/oz = 2268 grams.
Keisha should buy 2268 grams of cheese from the local market to make 5 batches of enchiladas.
