Answer:
Step-by-step explanation:
Let x be the portion of 60%
180 - x is the portion of 40%
0.60x + 0.40(180 - x) = 0.55(180)
0.60x + 72 - 0.40x = 99
0.20x = 27
x = 135
180 - 135 = 45
First brand = 45 gallons of 40%
Second Brand = 135 gallons of 60%
To find the number of reptiles you would set up the equation like this
90=2x+10, x being the number of reptiles. Solve for that equation and you'll be good. Hope this helps :)
