521Make the denominators the same.
57 =
1521 Number of wafers that Tina sold in the afternoon = 15 u
Number of wafers that Tina sold in the evening = 5 u
Number of more wafers that Tina sold in the afternoon than in the evening
= 15 u - 5 u
= 10 u
10 u = 40
1 u = 40 ÷ 10 = 4
Total number of wafers that Tina made
= 21 u
= 21 x 4
= 84
Answer(s): 84
