Kyle purchased a 20 lb. pumpkin for $5.95.
Cost per lb of pumpkin for Kyle = 5.95/ 12 = $0.496.
Elizabeth purchased a 15 lb. pumpkin for $5.00.
Cost per lb of pumpkin for Elizabeth = 5.00/15 = $0.333.
Elijah purchased an 8 oz. pumpkin for $ 0.16.
16 oz = 1 lb
8 oz = 0.5 lb.
Cost per lb of pumpkin for Elijah = 0.16/ 0.5 = $ 0.32.
<h3>Cost per lb of pumpkin for Elijah is $ 0.32 is the lowest price per lb of pumpkin .</h3><h3>Cost per lb of pumpkin for Kyle is $ $0.496 is the highest price per lb of pumpkin .</h3><h3>Therefore, Elijah got the best deal and Kyle got the worst deal.</h3>
Using a linear function, we have that:
a) The amount of water in the aquarium at 0 minutes is of 300 liters.
b) As time increases, the amount of water decreases at a rate of 60 liters per minute.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = ax + b
In which:
- a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, we have that the y-intercept is of 300, hence the amount of water in the aquarium at 0 minutes is of 300 liters.
The amount <u>decreases 60 liters in a minute,</u> hence:
As time increases, the amount of water decreases at a rate of 60 liters per minute.
