A home appliances factory produces 51 refrigerators every day. Let d represent the number of days the factory operates and r represent the total number of refrigerators produced.
+23251 The total number of refrigerators produced is the number of refrigerators produced each day times the number of days that of operation.
If 'r' represents the total number of refrigerators produced
and 'd' the number of days of production
and there are 51 refrigerators produced each day,
the appropriate formula is: r = 51·d
