23 =
1421 Number of cupcakes that Eva sold in the morning = 14 u
Number of cupcakes that Eva sold in the afternoon = 2 u
Number of more cupcakes that Eva sold in the morning than in the afternoon
= 14 u - 2 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Total number of cupcakes that Eva made
= 21 u
= 21 x 9
= 189
