Last month, Stacie spent \$57 on 4 allergy shots and 1 office visit. This month she spent \$9 after 1 office visit and a refund for 2 allergy shots from her insurance company. How much does an office visit cost? An allergy shot?

• Algebra -

57=V+4A
9=V-2A

subtract the equations
48=6A solve for A, then go to equation 2 and solve for V
