45 =
1215 Number of cookies that Natalie sold in the morning = 12 u
Number of cookies that Natalie sold in the afternoon = 2 u
Number of more cookies that Natalie sold in the morning than in the afternoon
= 12 u - 2 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Total number of cookies that Natalie made
= 15 u
= 15 x 6
= 90
