Andy and Pamela share some buttons.
56 of Andy's buttons is equal to
58 of Pamela's buttons. Given that Andy has 20 buttons less than Pamela, how many buttons do they have altogether?
56 of Andy's buttons = 58 of Pamela's buttons
Number of Andy's buttons = 6 u
Number of Pamela's buttons = 8 u
Number of buttons that Andy has less than Pamela
= 8 u - 6 u
= 2 u
2 u = 20
1 u = 20 ÷ 2 = 10
Total number of buttons
= 6 u + 8 u
= 14 u
= 14 x 10
= 140
Answer(s): 140
