Step-by-step explanation:
Answer:
every 180 seconds. Gina will respawn 9 times Helen will respawn 6 times and Jessica will respawn 10 times
X*80+y*60= 50*74
x +y =50 | * ( -60)
80x + 60y= 50*74
-60x - 60y=-50*60
---------------------------
20x= 50*(74-60)=50*14
x=50*14/20=35 pounds of 80 cents tea
y=50-35=15 pounds of 60 cents tea
