You work two jobs. you earn $9.80 per hour as a salesperson and $7.84 per hour stocking shelves. your combined earnings this month are $156.80. let x represent the number of hours worked stocking shelves and let y represent the number of hours worked in sales. graph the equation that models this situation.

The equation representing the situation can be given as:

Step-by-step explanation:

Given:

Earnings as a sales person = $9.80 per hour

Earnings from stocking shelves = $7.84

Total earning for the month = $ 156.80

To graph the equation that models this situation.

Solution:

Let represent the number of hours worked stocking shelves

Total earnings from stocking shelves in dollars  will be given as:

Let represent the number of hours worked as a sales person.

Total earnings as a sales person in dollars  will be given as:

Total earnings for the month can be given as:

Total earning for the month = $ 156.80

Thus, the equation representing the situation can be given as:

The above equation can be graphed with x-axis representing the number of hours worked stocking shelves and y-axis  representing the number of hours worked as a sales person.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
