You water the plants in your classroom at a constant rate. after 5 seconds, your watering can contains 58 ounces of water. fifteen seconds later, the can contains 28 ounces of water. a. write an equation that represents the amount y (in ounces) of water in the can after x seconds. b. how much water was in the can when you started watering the plants c. when is the watering can empty

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of 2 ounces lost per second. Now that we know the slope, we can answer the questions

A.  We can get the equation by finding the y int. (below) and writing it as y=-2x+68

B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= 68 ounces at the beginning.

C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: After 34 seconds.

entering that problem on the tube might get you an answer

the answer is 8/21

hope this
