Alocal civic group is selling t-shirts to raise funds for relay to life. they plan to sell 2500 t-shirts for $10. they consider raising the t-shirt price in order to earn more profit. for each $1 increase, they will sell 100 fewer t-shirts. let x represent the number of $1 increases. a. write a function, write a function, c(x), to represent the cost of one t-shirt based on the number of increases. b. write a function, t(x), to represent the number of t-shirts sold based on the number of increases. c. write a revenue function, r(x), for the t-shirt sell that could be used to maximize

a. Let us say that c(x) is the cost of one t shirt based on the number of increases therefore:

c = 10 + x

b. Say that t(x) is the number of t shirts sold based on the number of increases so:

 t = 2500 – 100 x

b. The revenue is simply the product:

r(x) = (10 + x) (2500 – 100 x)

Combining:

r(x) = 25000 – 1000 x + 2500 x – 100 x^2

r(x) = 25000 + 1500 x – 100 x^2

Taking the 1st derivative and setting dr / dx = 0 to get the maxima:

dr / dx = 1500 – 200 x

1500 = 200 x

x = 7.5

t = 2500 – 100 x = 2500 – 100 (7.5) = 1750

Hence 1750 shirts should be sold.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
