"Sam García has a monthly income of $300. After reviewing his expenses he came up with the following categories and their percentages: clothes 30%, food and snacks 23%, cell phone 14%, transportation 10%, gym 10%, movies 8% and apps 5%"

1. Calculate the expenses

2. Calculate Sam's net income

Step-by-step explanation:

Total income earned by Sam = $ 300

(i) Expense calculation,

Clothes expense = 30 % = 30 % (300) = $ 90

Food and snacks expense = 23 % = 23 % (300) = $ 69

Cell phone expense = 14% = 14% (300) = $ 42

Transportation expense = 10% = 10% (300) = $ 30

Gym expense = 10% = $ 30

Movies expense = 8% = 8% (300) = $ 24

Apps expense = 5% = 5% (300) = $ 15

Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300

(ii) Sam's net income is the profir earned  after his expense.

Net income = 300 - 300 = $ 0

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
