tatyana61 [14]
He needs 1080 I believe so 38
because 1042 divided for 45 museums would be 23.15 meaning it wouldn't be the same amount for all
but if they get 38 pictures (1080) and divide it between the 45 museums it would be an even number of 24

How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 40% antifreeze
nexus9112 [7]

Let the necessary amount of water be x.  Then (1.00)(1 gallon antifreeze) = 0.40(x+1 gallon), or 1 = .40x + .40.  Combining like terms:  0.60 = 0.40x.

Then x = 0.60 / 0.40 = 1.5.

Adding 1.5 gallons of water to that 1 gallon of pure antifreeze results in 2.5 gallons of 40% antifreeze.
