23 =
1421 Number of cupcakes that Fanny sold in the afternoon = 14 u
Number of cupcakes that Fanny sold in the evening = 5 u
Number of more cupcakes that Fanny sold in the afternoon than in the evening
= 14 u - 5 u
= 9 u
9 u = 99
1 u = 99 ÷ 9 = 11
Total number of cupcakes that Fanny made
= 21 u
= 21 x 11
= 231
