1015 Number of cookies that Xandra sold in the morning = 10 u
Number of cookies that Xandra sold in the afternoon = 2 u
Number of more cookies that Xandra sold in the morning than in the afternoon
= 10 u - 2 u
= 8 u
8 u = 64
1 u = 64 ÷ 8 = 8
Total number of cookies that Xandra made
= 15 u
= 15 x 8
= 120
