Answer 1

The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2

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
