Answer:
16 for Sol A and 24 for Sol B
Step-by-step explanation:
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 40 y = 40 - x
.60x + .85y = .75(40)
.60x + .85y = 30 Multiply both sides of the equation by 100 to remove the decimal points.
60x + 85y = 3000
60x + 85(40 - x) = 3000
60x + 3400 - 85x = 3000
-25x = -400
x = 16 ounces
y = 40 - 16
y = 24 ounces

Step-by-step explanation:
Your question isn't complete but let's help out by giving some values to the question.
Let's say there are 230 students in a school. This number is 15% more than it was last year. Calculate the number of students last year.
Let the number of students last year be x.
Since there's a 15% increase, this implies that (100% + 15%) = 115% of x equals to 230. This will be:
115% of x = 230
115% × x = 230
115/100 × x = 230
1.15x = 230
x = 230/1.15
x = 200
There were 200 students last year.
Just assign the missing values and use the above method and you'll get your answer.
