Dylan recently started a high end dog biscuit bakery. She found a storefront location for her store that cost her $36,000 and on the ingredients for her dog biscuits (a super secret recipe) cost $1.10 per biscuit. If she plans on selling the dog biscuits for $7.50 a piece, how many biscuits will she have to sell before she breaks even?

She would have to sell 5625 dog biscuits.

7.50 · 5625 = 42,187.50

1.10 · 5625 = 6,187.50

6,187.5 + 36,000 = 42,187.50

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
