Question 1
Marie mixes 16 liters of 18% acid solution with a 27% acid solution, which results in 21% acid solution.
Let x represent the number of liters of 27% solution used and let y represent the number of liters of mixture. Which system of equations can be used to find the number of liters of 27% acid solution in the mixture?
y = x + 16; 0.27y = 0.21x + 2.88
y = x + 16; 0.21y = 0.27x + 2.88
y = x + 16; 0.21y = 0.27x + 4.32
y = x + 16; 0.27y + 2.88x = 0.21
Question 2
Amy mixes 12 liters of 16% acid solution with a 40% acid solution, which results in 32% acid solution.
Let x represent the number of liters of 40% solution used and let y represent the number of liters of mixture. Which system of equations can be used to find the number of liters of 40% acid solution in the mixture?
y = x + 12; 0.4y = 0.32x + 3.84
y = x + 12; 0.4y = 0.32x + 1.92
y = x + 12; 0.32y = 0.4x + 4.8
y = x + 12; 0.32y = 0.4x + 1.92
Question 3
Amy mixes 12 liters of 16% acid solution with a 40% acid solution to make a 32% acid solution.
How many liters of 40% solution did she use?
36 liters
24 liters
16 liters
4.8 liters
Question 4
Amy mixes 12 liters of 26% acid solution with a 40% acid solution to make a 33% acid solution.
How many liters of 40% solution did she use?
36 liters
12 liters
16 liters
4.8 liters
Question 5
Marie mixes 16 liters of 18% acid solution with a 27% acid solution to make a 21% acid solution.
How many liters of 27% solution did she use?
8 liters
12 liters
20 points :)
