She needs to scale the recipe up from
8 to 60 people
+8k+=+60+
+k+=+60%2F8+
+k+=+7.5+
+5%2A9k+=+45k+
+45%2A7.5+=+337.5+ ounces
+337.5%2F16+=+21.1+
21 pounds of tomatoes are needed
-----------------------------------
Let +c+ = number of cups needed for 60 people
+c%2Ak+=+60+
+c%2A7.5+=+60+
+c+=+60%2F7.5+
+c+=+8+
8 cups of onions are needed
Use conversion
[ pints / cup ]*8 = pints needed
You can look up conversion
