Question

John has $10 more than Lupe and Lupe has 5% more than Chonita. The total amount of money is $87. Find how much monye does John have?

Answer 1

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
