Abe amodeo, a nuclear physicist, needs 6060 liters of a 6060% acid solution. he currently has a 40 %40% solution and a 70 %70% solution. how many liters of each does he need to make the needed 6060 liters of 6060% acid solution?

Let x = the amount of 50% solution used Let y = the amount of 70% solution used   Since he needs 60 liters total x + y = 60   Since he needs 60% acid solution 0.5x + 0.7y = 60 * 0.6   Now we you have two equations, solve the system.   Multiply both sides of the second equation by 2 x + 1.4 y = 72   Subtract the new equation by the first equation 0.4 y = 12   Solve for y   y = 30   Solve for x   x = 30   He needs 30 L of 50% acid solution and 30 L of 70% acid solution

the answer is true.

this statement is true.

I’m pretty sure it’s false i’m not sure
