47 =
1221 Number of biscuits that Barbara sold in the morning = 12 u
Number of biscuits that Barbara sold in the evening = 4 u
Number of more biscuits that Barbara sold in the morning than in the evening
= 12 u - 4 u
= 8 u
8 u = 32
1 u = 32 ÷ 8 = 4
Total number of biscuits that Barbara made
= 21 u
= 21 x 4
= 84
