<span><span>The total cost of a sandwich, a glass of milk, and an apple is $2.35 What was the price of each, if the sandwich cost twice as much as the milk and the apple cost 90 cents less than the sandwich?
</span><span>
<span>s=cost of the sandwich.
m=s/2
a=s-.9
s + s/2 + s-.9 = 2.35
2s+s+2s-1.8=4.7 Multiply each side by 2.
5s-1.8=4.7
5s=6.5
s=$1.30
m=$.65
a=$.40

Flow is given as, F = - 4 gallon per minute into small tank.
( Since, flow is negative )
Volume of oil in large tank, V = 600 gallons.
Now,
Volume of oil has been moved :
Therefore, 128 gallons of oil has been moved to small tank.
Hence, this is the required solution.
