Leonard it sells small watermelons for seven dollars each and large watermelons for $10 each one day the number of small waterme
1 answer:
He sold 32 small watermelons and 17 large watermelons.
Step-by-step explanation:
Let,
Small watermelons = x
Large watermelons = y
Cost of one small watermelon = $7
Cost of one large watermelon = $10
According to given statement;
x = y+15 Eqn 1
7x+10y=394 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 17
Putting y=17 in Eqn 1
He sold 32 small watermelons and 17 large watermelons.

Answer:
Step-by-step explanation:
If an exponential function is in the form of y = a(b)ˣ,
a = Initial quantity
b = Growth factor
x = Duration
Condition for exponential growth → b > 1
Condition for exponential decay → 0 < b < 1
Now we ca apply this condition in the given functions,
1).
Here, (1 + 0.45) = 1.45 > 1
Therefore, It's an exponential growth.
2).
Here, (0.85) is between 0 and 1,
Therefore, it's an exponential decay.
3). y = (1 - 0.03)ˣ + 4
Here, (1 - 0.03) = 0.97
And 0 < 0.97 < 1
Therefore, It's an exponential decay.
4). y = 0.5(1.2)ˣ + 2
Here, 1.2 > 1
Therefore, it's an exponential growth.
