By what percent will the product of two numbers increase if one of them is increased by 15% and the other is increased by 40%?

Marysya12 [62]4 years ago

Answer:

61% increase

Step-by-step explanation:

Product of two numbers = x * y = xy

(x + 15%) * (y + 40%)

Due to the fact that x and y are variables, we can add the percents to them

1.15x * 1.4y

Multiply

1.61xy

Calculate percent increase

1.61xy (new amount) - xy (original amount)

------------------------------------------------------------      * 100

                   xy (original amount)

Simplify

.61xy

---------  * 100      =     61%

  xy

61% increase

Hope this helps :) Let me know if you have any questions about my answer.

Two linear equations can have no solutions, exactly one solution or infinitely many solutions. There will be no solution if the lines are parallel on a graph. There will be exactly one solution if the lines intersect each other on a single point. And finally, there will be infinite solutions if the lines overlap each other perfectly.

A single line however has infinite ordered pair solutions as the line travels infinitely in both directions on the coordinate plane. For example, using the equation y=3x, for any real value of x, we will get a real value for y.

Linear inequalities with two variables have infinitely many solutions. We can use the inequality y>3x as an example. For any real value of x, we will get a real value for y.

I hope this helps!
