Answer:
She will buy 6 Christmas balls and 4 star shaped Christmas snowmen
Step-by-step explanation:
Let s = star shaped Christmas snowman
and let b = Christmas ball
We know that each snowman will cost $3, so therefore it will be 3s and each ball will equal $4, resulting in 4b
Thus the equation would be 36 = 3s + 4b
and s + b = 10
Solve for one so s = 10 - b and plug it into the other equation
36 = 3(10 - b) + 4b
36 = 30 - 3b + 4b
36 = 30 + b
6 = b
Plug b into one of the equations to solve for s
s + 6 = 10
s = 4
