Answer:
Pants cost $20 and tee-shirts $10.
Step-by-step explanation:
For Sam 3t + 2p = 70
For Jessica 4t + p = 60
Take 2 times Jessica's equation and subtract Sam's
8t + 2p = 120
3t + 2p = 70
5t = 50
t = 10
3(10) + 2p = 70
30 + 2p = 70
2p = 40
p = 20
the first and third should be the correct answer I hope this helps
