Answer:Yuan received $50 last year
Explanation:
Yuan receives money from his relatives every year on his birthday.
Let x represent the amount of money that Yuan received last year on his birthday.
This year, Yuan received a total of $56. The amount that he received this year is 12% more than he received last year. This means that
the increment on the amount that he received last year is would be
12/100×x = 0.12x. Therefore,
x + 0.12x = 56
1.12x = 56
x = 56/1.12 = $50
