2025 Number of cookies that Emma sold in the morning = 20 u
Number of cookies that Emma sold in the evening = 3 u
Number of more cookies that Emma sold in the morning than in the evening
= 20 u - 3 u
= 17 u
17 u = 170
1 u = 170 ÷ 17 = 10
Total number of cookies that Emma made
= 25 u
= 25 x 10
= 250
