Pls give us model to this question:
Aleks [24]
Rent = 360
Groceries and hhold goods = 240

Given: 
Weekly pay = 720
Groceries and household goods = 1/3 of weekly pay
Rent = 3/4 of money net from groceries.

720 * 1/3 = (720*1)/3 = 240 groceries and household goods
720 - 240 = 480 remaining money for rent
480 * 3/4 = (480*3)/4 = 1440/4 = 360 rental payment
480 - 360 = 120 remaining money.

Joanne spends 360 for rent and 240 for groceries and hhold goods.

Is my answer correct
kondor19780726 [428]

Answer:

Yes, you are correct.

Step-by-step explanation:

\text{Let the number of puzzle solved by Child B is} x\text{.}

\text{Then the average number of puzzle solved is}

\frac{5x+x+(x+4)}{3}=13

\frac{7x+4}{3}=13

7x+4=39

7x=35

x=5

\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25

\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}
