Answer:
He earn $40
Step-by-step explanation:
To solve this problem, we first have to calculate how much it spends to make each pie
cups of fruit = 5
5 * $0.75 = $3.75
This means that per pie he spends $ 3.75 on cups of fruit and $ 2.50 on pie crust
If we add them together we will get how much he spends for each pie
$3.75 + $2.50 = $6.25
Now to the price that the pie sells we subtract this value to know how much you earn for each pie
$10.25 - $6.25 = $4
if he sold 10 pies we multiply this number by 10 and we will get his total profit
$4 * 10 = $40
He earn $40
The solutions to the given system of equations is (0, -6) and (1, -5)
<h3>Simultaneous equations</h3>
From the question, we are to determine the solutions to the given system of equations
The equations are
x − y = 6 --------- (1)
y = x² −6 ---------- (2)
From equation (1)
x - y = 6
∴ x = 6 + y ------- (3)
Substitute into equation (2)
y = x² −6
y = (6+y)² −6
y = (6+y)(6+y) -6
y = 36 + 6y + 6y +y² -6
y = 36 + 12y + y² - 6
Simplifying
y² + 12y - y + 30 = 0
y² + 11y + 30 = 0
Solve quadratically
y² + 11y + 30 = 0
y² + 6y + 5y + 30 = 0
y(y +6) +5 (y +6) = 0
(y + 5)(y + 6) = 0
y + 5 = 0 OR y + 6 = 0
y = -5 OR y = -6
Substitute the values of y into equation (3)
x = 6 + y
When y = -5
x = 6 + (-5)
x = 6 -5
x = 1
When y = -6
x = 6 + (-6)
x = 6 -6
x = 0
∴ When x = 0, y = -6 and when x = 1, y = -5
Hence, the solutions to the given system of equations is (0, -6) and (1, -5)

to round to nearest thousand
we see the hundredth digit
So the answer is 1,845,000
and to round to nearest 100,000
we see the ten thousandth digit
So the answer should be 1,800,000
