li started a pool cleaning business. She purchased cleaning supplies and charged the same amount for each pool cleaned. The expression −243+24x−243+24x represents the profit Tali has earned from cleaning pools. Which expression represents the total amount Tali earns from pool cleaning?answer is one of these (x , 24, -243 , 24x )

Tali makes a profit of â’243+24xâ’243+24x. Since she made a profit and not a loss, the positive terms are the total amount paid to her for all the pools that she cleaned. On the other hand, the negative terms would be the cost of the cleaning supplies that she purchased for the work Hence, the total amount Tali earns from pool cleaning is 24x+24x = 48x However since she charged the same amount for each pool cleaned, it means that she charged x amount for 48 pools. Answer is "x"
