The amount of money John has is $ 36.08
If it is known that John has $ 10 more than Lupe has, and Lupe in turn has 5% more than Chonita, and the total sum that between the three of them is $ 87, we formulate the following to know the amount of money of John.
($ 10 + L) + L + L / 1.05 = $ 87 We solve for L which would then be the value of Lupe's money
$ 10 + 2L + L / 1.05 = $ 87
62L / 21 = $ 77
L = $ 26.08
John's money
$ 26.08 + $ 10
$ 36.08
