Ali wanted to figure out the selling price for the custom paperweights he planned to sell. he found that at a price of $5.00, he could sell 20 units; at a price of $10.00, he could sell 15 units; and at a price of $20.00, he could sell 5 units. based on these numbers, how could ali make the maximum profit? sell at $5.00 sell only 15 units sell at $10.00 sell less than 20 units sell at $20.00

He should sell at $10.00.

Hope this helped<3

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
