45 =
1215 Number of wafers that Dana sold in the morning = 12 u
Number of wafers that Dana sold in the afternoon = 2 u
Number of more wafers that Dana sold in the morning than in the afternoon
= 12 u - 2 u
= 10 u
10 u = 100
1 u = 100 ÷ 10 = 10
Total number of wafers that Dana made
= 15 u
= 15 x 10
= 150
Answer(s): 150
