Suppose the clean water of a stream flows into Lake Alpha, then into Lake Beta, and then further downstream. The in and out flow for each lake is 200 liters per hour. Lake Alpha contains 100 thousand liters of water, and Lake Beta contains 200 thousand liters of water. A truck with 200 kilograms of Kool-Aid drink mix crashes into Lake Alpha. Assume that the water is being continually mixed perfectly by the stream. a. Let x be the amount of Kool-Aid, in kilograms, in Lake Alpha hours after the crash. Find a formula for the rate of change in the amount of Kool-Aid, x/, in terms of the amount of Kool-Aid in the lake x. x= kg/hour b. Find a formula for the amount of Kool-Aid, in kilograms, in Lake Alpha hours after the crash. x()= kg c. Let y be the amount of Kool-Aid, in kilograms, in Lake Beta hours after the crash. d. Find a formula for the rate of change in the amount of Kool-Aid, y/, in terms of the amounts x, y. y= kg/hour Find a formula for the amount of Kool-Aid in Lake Beta hours after the crash. y()= kg

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
