Answer: 35 t shirts
Step-by-step explanation:
Let number of t shirts be x
Let profit made be y
On main street, the store costs $650,
Selling the t shirt at $32 per 1
He would make a revenue of 32x
Profit = revenue - cost accrued
y1 = 32x - 650
On Broad street, the store costs $440,
Selling the t shirt at $26 per 1
He would make a revenue of 26x
Profit = revenue - cost accrued
y2 = 26x - 440
To make same profit on either location
y1 = y2
32x - 650 =26x - 440
32x -26x = -440+650
6x = 210
x = 210/6
= 35 t shirts
<em>Note:</em>
<em>Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.</em>
Question 2
Answer:
The equation in the standard form is:
Please also check the attached graph.
Step-by-step explanation:
We know that the equation in the standard form is
Ax + By = C
where x and y are variables and A, B and C are constants
Given
To determine
- Write the equation in the standard form
We know that the slope-intercept form of the line equation

where
In our case:
substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation
y = mx+b
y = -2/3x + (-4)
y = -2/3x - 4
Writing the equation in the standard form
2/3x + y = -4
Therefore, the equation in the standard form is:
Please also check the attached graph.
So you already know the difference between the new number and original number, so all you have to do now is plug it in to this: Percentage Change=Difference/Original Number x100. So 17.99/257=.07x100 which equals 7%. So B is the correct answer.
Answer:
<em>81 </em>
Step-by-step explanation:
25, 36, 49, 64, ...
36 - 25 = 11
49 - 36 = 13 = 11 + 2
64 - 49 = 15 = 13 + 2
64 + 15 + 2 = <em>81</em>
