Muiltiply x and y on both problems by two.
Answer:
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
Step-by-step explanation:
Let
x ----> the unit cost of one toy reindeer
y ----> the unit cost of one box of cookies
we know that
----> equation A
----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (3,2)
see the attached figure
therefore
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2

Answer:
69.2°
Step-by-step explanation:
From the diagram attached to this solution. We shall be considering
Tan θ = opp/adj
Where θ = ?
Opp = AC = 385feet
Adj = AB = 146feet
Tan θ = AC/AB
Tan θ = 385/146
Tan θ = 2.636
θ = tan^-1 2.636
θ = 69.225
θ = 69.2°
Hence the angle to the horizon is 69.2°
