Jennifer picked up these two videogames for a bargain. Normally,each costs $30. But today therewere 30% off. If she also paid8.2

andreev551 [17]

Solution

Step 1

Write an expression for the sales tax she paid and the percentage off

$\begin{gathered} \text{Percentage off =30\%. Therefore, the actual \% left = 100 -30 = 70\%} \\ \frac{100}{70}=\frac{\cos t\text{ of both video games}}{x} \\ \text{where x = cost of video games after the \% off} \\ \end{gathered}$ $\begin{gathered} \text{For the sales tax} \\ \frac{100}{8.25}=\frac{\cos t\text{ of two shirts}}{y} \\ \text{where y = amount of sales tax paid} \end{gathered}$

Step 2

Find her total bill after substitution

$\begin{gathered} \text{Amount paid after 30\% off will be} \\ \frac{100}{70}=\frac{60}{x} \\ 4200\text{ = 100x} \\ x=\text{ }\frac{4200}{100} \\ x=42\text{ dollars} \end{gathered}$ $\begin{gathered} \text{Amount of sales tax} \\ \frac{100}{8.25}=\frac{60}{y} \\ 495\text{ = 100y} \\ y\text{ =\$4.95} \end{gathered}$

Her total bill thereore = 42 +4.95 =$46.95

You are putting away money to spend at the school carnival. On day 6, you had $5. You were able to save

skad [1K]

Answer:

We have the equation of the line as;

y = 1.80x - 5.80

Step-by-step explanation:

Let us have a plot of the amount saved in dollars to the day number

So we have the amount as y axis values and the day as x axis values

from the question, we can identify the points as;

(6,5) and (11,14)

Mathematically the equation of a straight line can be represented by the equation;

y = mx + b

where m is the slope and b is the y intercept

So, we calculate the slope using the two points above

We have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,5)

(x2,y2) = (11,14)

m = (14-5)/(11-6) = 9/5 = 1.8

So we have the equation as;

y = 1.80x + c

To get the value of c, we use any of the two points

Let us use the point (6,5)

we substitute 6 for x and 5 for y

So, we have ;

5 = 1.8(6) + c

c = 5-1.8(6)

c = -5.8

So we have the equation as;

y = 1.80x - 5.80
