Answer:
150 mL
Step-by-step explanation:
We need a mixture that is at 50%, now we have 200 mL at 35% and another mixture that is at 70%, that is, we must calculate how much of this mixture is added, by the following equation
200 * 35% + x * 70% = 50% (x + 200)
70 + 0.7 * x = 0.5 * x + 100
0.7 * x - 0.5 * x = 100 - 70
0.2 * x = 30
x = 30 / 0.2
x = 150
150 mL must be added so that the mixture is 50%.
Each of the first 3 letters can be chosen from the 23 letters, {A, B, C, …, U, V, W}, so there are 23³ possible choices.
The first 2 digits can be any number from {0, 1, 2, …, 9}, so there are 10² choices.
The last digit cannot be 0 or 9, so you can select from {1, 2, 3, …, 8} which gives 8 choices.
Then the total number of PINs that you can make is
23³ × 10² × 8 = 9,733,600
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given,
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50
Maximum people that can be hold by theater = 1000
Therefore;
The maximum number of people can be 1000 or less than that.
As they want to revenue to be more than 15,000 therefore,
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
