Zach had to make bracelets for Student Council. He made 10 of them on Monday and 2/5 of them on Tuesday. Zach completed the remaining 1/2 on Wednesday. How many bracelets for Student Council did Zach have to make?

Tuesday = 2/5 = 4/10 of the total.
Wednesday = 1/2 X 3/5 = 3/10 of total.
Monday = 10 = 1/2 x 3/5 = 3/10 of total.
Wednesday + Monday total = 20.
Do not understand how to solve Tuesday to get an even number of bracelets. How do you solve for Tuesday?
