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

$3x+2y=13.00$ ----> equation A

$2x+2y=10.00$ ----> 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
