Answer: Our required linear equation would be
Step-by-step explanation:
Since we have given that
Cost of deep fried bananas on a stick = $1.00
Number of sales reached = 100 per day
Cost of deep fried bananas on a stick becomes = $2.00
Number of sales reached = 52 per day.
Let x is the number of dollars each.
Let y be the number of vendors sale.
So, we need to form the linear equation:
As we know the formula for two point slope form:
Hence, our required linear equation would be
Answer:
(2, -7)
x = 2
y = -7
Step-by-step explanation:
Let's solve this system of equations by elimination.
Start by multiplying the first equation by 2:
Next, multiply the second equation by 3:
Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:
Divide both sides by 23
Substitute 2 for "x" to solve for "y".
Subtract 8 from both sides:
Divide both sides by 3:
Therefore the answer is:
Additional Comments:
Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.
