Party A deposits 50 yuan in the bank and 88 yuan in the bank again and again. After that, Party A deposits 5 yuan a month and 12 yuan has been deposited. A few months later, Party B deposits twice as much as Party A deposits equation

Set m months
(50+5M)X2=88+12M
Solving the equation: M = 6
A: six months

The total price of two pieces of clothes is 500 yuan. Party A will make a 50% profit while Party B will make a 40% profit. Two pieces of clothes will be sold at a 10% discount and the profit will be 157 yuan. What are the costs of Party A and Party B?

If a costs X Yuan, there will be
[X(1+50%)+(500-X)*(1+40%)]*0.9=500+157
The solution is x = 300
Then the cost of B is 500-300 = 200 yuan

A garment in a clothing store is sold at a fixed price according to 50% of the profit. As a result, it is sold at a 20% discount and still earns 120 yuan. How much is the cost price of this garment?

600 yuan

The cost of two pieces of clothing is 500 yuan. Party A sets the price according to 50% of the profit. Party B sets the price according to 40% of the profit
Don't think about the formula, think about it! For example, (1 + 50%) x * 0.9 + (1 + 40%) (500-x) * 0.9 = 500 + 157
(1 + 50%) x why is this? Isn't it 50% profit? Why use 50% * x?

Suppose the purchase price of clothing A is x, then the purchase price of clothing B is 500-x. (1 + 50%) X. This is the original price, which is calculated according to 50% profit. Because the back is 10% off, it is (1 + 50%) x * 0.9. (1 + 40%) (500-x) this is the original price, which is calculated according to 40% profit. Because the back is 10% off, it is (1 + 40%) (500-x)

(0.55-1/5)/(5/7*4.9)

All into fractions and then operation
=（55/100-20/100）/(5/7×49/10)
=35/100 / 7/2
=1/10
