Given information: If the price is set at $1.25 per drink, then 400 drinks are sold. Calculation: As it is provided that if the price is set at $1.25 per drink, then 400 drinks are sold. Let x represent the number of drinks that are sold if the price is set to $2.50 per drink. Set up a proportion by writing two equivalent ratios: 1.25400=2.5x Multiply by LCD, that is 400x in above equation. 400x⋅1.25400=400x⋅2.5x 400x⋅1.25400=400x⋅2.5x Solve the above linear equation. 1.25x=2.5⋅400 1.25x=1000 x=10001.25 x=800 Thus, the number of drinks that are sold is 800.

Step 1  For example, look at this equation:  ab=cd  For the equation  1.25400=2.5x  Since the denominators are also the same here, b×d, you can remove them and say that:  a×b=b×c  The cross product is  1.25×x=400×2.5  Solving  x=400×2.51.25  reducing  x=800

Step 1 1.25400=2.5x Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 400x, the least common multiple of 400, x x×1.25=400×2.5 Multiply 400 and 2.5 to get 1000 x×1.25=1000 Divide both sides by 1.25 x=10001.25 Expand 10001.25 by multiplying both numerator and the denominator by 100. x=100000125 Divide 100000 by 125 to get 800. x=800
