2835 Number of cupcakes that Irene sold in the morning = 28 u
Number of cupcakes that Irene sold in the evening = 2 u
Number of more cupcakes that Irene sold in the morning than in the evening
= 28 u - 2 u
= 26 u
26 u = 286
1 u = 286 ÷ 26 = 11
Total number of cupcakes that Irene made
= 35 u
= 35 x 11
= 385
