The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
The line passes through the point (1, 8) and (2, 16), hence:
The equation of the line is given by y =8x

Hello! 6 3/4 is equivalent to 6.75. So basically, you would be paying 6.75% tax. To find the amount of tax, multiply the price by the percentage rate. 2,305 * 6.75% (0.0675) is 155.5875 or 155.59 when rounded to the nearest hundredth. You would pay $155.59 in tax. The answer is D.
Using the graph of the scenario, the edge of the kiosk is 20 feet far from the entrance.
<h3>How to determine the distance of the edge ?</h3>
The y value is given as:
y = 24
From the graph of this question (see attachment), we have the following coordinate
(x,y) = (20,24)
This means that the edge of the kiosk is 20 feet far from the entrance.

Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.
To answer the question, we need to know what probability is
<h3>What is probability?</h3>
This is the likelihood for an event to occur. It is given by
P(event) = number of required outcomes/total number of outcomes
Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.
<h3>Probability that all of Erica's flights will be on time</h3>
So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)
= [P(flight)]⁴
= (90%)⁴
= (0.9)⁴
= 0.656
≅ 0.66
= 66%
So, the probability that all of Erica's flights will be on time is B 66%.
