Question

5 hockey pucks and 3 hockey sticks cost $23.
5 hockey pucks and and 1 hockey stick cost $20.
How much does one hockey puck cost?
Please show your work. Thank you in advance.

Answer 1

p = pucks and h = sticks

5p + 3h = 23 (1)
5p + h = 20 (2)

solve simultaneously

(1) -(2)

2h = 3

h = 1.50 sub back into (2) to find p 5p + 1.50 = 20 5p = 18.50 p = 3. 70

a hockey stick costs $1.50 a puck costs 3.70

Answer 2

Thank you.
