Gordon has a summer job as a tour guide. He makes $10/h for up to 40 h each
week. If he works more than 40 h, he makes 1.5 times his hourly pay, or
$15/h, for each hour over 40 h. Make a graph and function that shows Gordon’s weekly earnings E based on the number of hours n he worked.

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)

(a + b) (a^2 - a b + b^2)
