Answer: C

: Miriam multiplied correctly, but her third fraction should be .S

Step-by-step explanation: Miriam used the unit conversation upside down. The 7000 g should have been multiplied by 1oz/28.35g

The grams cancel and the division of 7000 be 28.35 results in 246.91 oz Round to 252oz.

Alternative: 7kg (2.21 lb/kg)(16oz/lb)=252.5oz

The kg and lbs cancel and the amount of ounces remains.
