You set up a lemonade stand to raise money for your soccer tournament. You plan to sell cups of lemonade for $1.50/each. Your recipe calls for 8 lemons, 2 cups of sugar and 8 cups of water to yield 10 cups of lemonade.
You open your lemonade stand with 80 lemons, 3 bags of sugar containing 6 cups each, and 10 gallons of water (16 cups per gallon). What is the maximum you can make with the supplies on hand?
A) $112.50
B) $135
C) $75
D) $90

The maximum you can make with the supplies on hand is:

Explanation:

The requirements for the recipe are: 8 lemons, 2 cups of sugar and 8 cups of water to yield 10 cups of lemonade, so you must divide the total supplies into the requirements for the recipe and see how many glasses each reaches:

As you can see, although in water there are supplies for 200 glasses of lemonade or in lemons there are supplies for 100, sugar only allows 90 glasses of lemonade, so you must use this value to calculate the income from the sale of lemonade, the which, since it is worth $ 1.50 per glass you have:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
