2028 Number of wafers that Nora sold in the afternoon = 20 u
Number of wafers that Nora sold in the evening = 5 u
Number of more wafers that Nora sold in the afternoon than in the evening
= 20 u - 5 u
= 15 u
15 u = 30
1 u = 30 ÷ 15 = 2
Total number of wafers that Nora made
= 28 u
= 28 x 2
= 56
Answer(s): 56
