Im assuming the question is asking: if she collected $22 in sales tax what was the cost of the items her store sold. you should make sure you type the question correctly otherwise it'll be hard to answer.
going with my assumption of what the question is, we want to find the total cost of all items her story sold. let that cost be c. since there is 5% sales tax on everything and we know the sales tax is worth $22,m we have:
5%(c) = 22
dividing both sides by 5% (or .05) gives:
c = $440
Answer:
Step-by-step explanation:
1. You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
2. Point-Slope Form: y - y1 = m(x - x1)
Standard Form: ax + by = c
5x - 2y = 10
-2y = -5x + 10
y = (5/2)x - 5 The slope is 5/2.
y - 2 = (-5/2)(x - 10)
y = (-5/2)x + 25 + 2
y = (-5/2)x + 27 The slope is -5/2.
y = (-5/2)x - 10 The slope is -5/2.
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
From the graph:
The cost for a group of 16 friends is $2500, while for a group of 10 friends is $1300.
Cost per passenger for 16 friend = $2500 / 16 = $156.25
Cost per passenger for 10 friend = $1300 / 10 = $130
The difference in price = $156.25 - $130 = $26.25
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25

To answer, it is assumed that e here is the Euler number which is equal to 2.718. Substitute this value to the e of the second equation to get the value of b.
b = 0.5(2.718^2) = 3.6945
Then, we substitute this value to the first equation to get the value of a.
a = 4(3.6945^2) = 54.498
Thus, the answer is approximately equal to 54.5.
A is not true :) Hope i helped!
