2432 Number of cookies that Diana sold in the morning = 24 u
Number of cookies that Diana sold in the evening = 3 u
Number of more cookies that Diana sold in the morning than in the evening
= 24 u - 3 u
= 21 u
21 u = 168
1 u = 168 ÷ 21 = 8
Total number of cookies that Diana made
= 32 u
= 32 x 8
= 256
