The principal is the loan amount, $1,000
Answer:
An apple costs $2 and a banana costs $1.
Step-by-step explanation:
x = cost of 1 apple and y = cost of 1 banana. So:-
2x + y = 5
2x + 3y = 7
Subtract the first equation from the second. We get:-
2y = 2
y = 1
and since 2x + y = 5, 2 x + 1 = 5 and
x = $2.

(3 degrees Celsius - 5 degrees Celsius)= -2 degrees Celsius
Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
