2molAl3+ ions, while providing 3molSo42- ions;

3molMg2+ ions, and 3molSo42- ions per acre are provided;

The relationship between SO42- ions is 1:1.

In the solution containing 2molSO42- ions, 1molSO42- ions are provided by MgSO4, and the mass of MGSo4 is 120g.

Set up to purchase x box table tennis (x 5).

A sells Lu store y = 30 * 5 + 5 (x-5) = 5 x + 125 B store z =

1)y=z,5x+125=

x=2020 box balls when the silver bucket is round, the payment is the same.

2) 15 box balls, x = 15

y=5*15+125=200

z = A store collapse is cost-effective.

30 box balls, x = 30

y=5*30+125=275

z = B store is a good deal.
