Answer:
1.3 liters
Explanation:
So first off, lets find the amount of milileters of lotion there is.
To do this, take 8, and divide it in half:
8/2 = 4. So we know that 4 bottles of lotion each contain 150 militers of lotion.
We know that the other 4 bottles each contain 175 milileters of lotion.
Next, lets multiply the 150 and 175 by the four bottles:
150x4
=
600
175x4
=
700
Now lets add these two values together, to find the total amount of lotion:
700+600
=
1300
Remember, this problem asked for liters of lotion, not milileters. Lets recall that 1000 milileters are equivelent to 1 liter:
1300/1000
=
1.3
This is your answer!
Hope this helps! :)
