A farmer builds a fence for his chickens in the shape of a pentagon, as shown. Each of the 5 sides has equal
length, but the fence along the highway costs twice as
much as any one of the other 4 sides. If the total cost
of fencing was $1800, how much did the highway
fence cost?

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
