10×4+(x- 10)×8 = 5x+32
40+8x-80=5x+32
8x-5x=80+32-40
3x=72
x=24
5×24+32= 152 (piece)
A: There are 24 monkeys on Monkey Mountain, and they buy 152 peaches.
The price of this toy is X yuan.
The price of toys is three-fifths of Xiao Fang's money, and Xiao Fang's money is five-thirds of toys, which is (5/3) X.
The price of toys is two-thirds of all Xiaoming's money, and Xiaoming's money is two-thirds of toys, which is (3/2) X.
According to the situation of buying toys, Xiao Fang has more money than Xiao Ming. 20 yuan, make an equation:
[(5/3)x-x]-[(3/2)x-x]=20
(2/3)x-( 1/2)x=20
( 1/6)x=20
x= 120
Xiao Fang's remaining money is:
5/3× 120- 120
=200- 120
=80 yuan.
