Please I need help w this question. *Use and show formulas*

1) This St. Patrick’s Day at McGuinnes Pub they plan to sell 225 lbs. of corned beef dinners.
If they were able to purchase the beef for $3/lb. how much did they pay for it in total?

"2) If you want to markup the selling price by 300%, how much do you need to charge per pound of beef?
"

3) If they sell all of it at this price, how much revenue, and profit did they make on the beef alone?
Revenue=Total Sales Profit=Sales - Costs

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

answer: the answer is 127 degrees

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
