Let us set up the equation using the given information
Boys = x
Girls = √x
Boys + girls = 42
Equation: x + √x = 42
You can now work out this equation to solve for x, OR reason your way through it. By substituting numbers into the equation. Try 36
36 + √36 = 42
36 + 6 = 42
42 = 42
ANSWER: 36 Boys (and 6 girls)
Hope this helps! God bless!! :)

First you must find out how much you would get off of the original price with the discount. to do this you multiply 119 by .40 (the decimal form of the percentage) to get 47.6.
