Answer:
y = 0.2x + 250
Step-by-step explanation:
let the sales be x and y be earnings
thus,
given
x₁ = $3,500 ; y₁ = $950
and,
x₂ = $2,800 ; y₂ = $810
Now,
the standard line equation is given as:
y = mx + c
here,
m is the slope
c is the constant
also,
m = 
or
m = 
or
m = 0.2
substituting the value of 'm' in the equation, we get
y = 0.2x + c
now,
substituting the x₁ = $3,500 and y₁ = $950 in the above equation, we get
$950 = 0.2 × $3,500 + c
or
$950 = $700 + c
or
c = $250
hence,
The equation comes out as:
y = 0.2x + 250
Answer:

Step-by-step explanation:
Let
x ----> the number of lions
y ----> the number f tigers
z ----> the number of zebras
we know that
----> equation A
Remember that


To find out the number of lions, multiply the total animals by the percentage of lions

To find out the number of zebras, multiply the total animals by the percentage of zebras

Substitute the value of x and the value of z in equation A and solve for y



Answer:
n-58
Step-by-step explanation:
What is the digit at the hundred thousands place? It is 2. Is the digit to the right of it less than 5? No, 5 is 5. So replace the digits to the right of 2 with 0, and change the 2 to 3.
Answer: 300,000
