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.
