Your club is selling hats and t-shirts to raise money for juvenile diabetes. you have already spent $240 on the hats and t-shirts and plan to sell the hats for $5 each and the t-shirts for $12 each. let x represent number of hats sold and y represent number of t-shirts sold. you must sell enough so that you earn more than the $240 you have already spent. which of the following inequalities represents this situation?

The number of hats sold = x

The number of t-shirts sold = y

Cost of selling of each hat = $5 and

Cost of selling of each t-shirt = $12.

Cost of x hats at the rate $5 each = 5x and

Cost of y t-shirts at the rate $12 each = 12y.

Total cost of x hats and y t-shirts = 5x+12y.

Total amount was spent = $240.

Therefore, cost of x hats and y t-shirts should be greater than or equal to 240.

the equivalent expression are always the hardest ones but you look at the gcf also

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,
