The linear equation used to solve the problem is t = 2 + 1.29a and total cost to download 30 songs is $ 40.7
<em><u>Solution:</u></em>
Given that music app charges $2 to download the app plus $1.29 per song downloaded
To find: write and solve a linear equation to find the total cost to download 30 songs
Let us first write a expression for total cost
Let "a" be the number of songs downloaded
So we can frame a equation as:
total cost = initial charge + cost of 1 song download x number of songs downloaded

total cost = 2 + 1.29a
If "t" represents the total cost, then the linear equation is:
t = 2 + 1.29a
<em><u>finding the total cost to download 30 songs:</u></em>
Here a = 30
Substitute a = 30 in above formula
total cost = 2 + 1.29(30)
total cost = 2 + 38.7
total cost = 40.7
Thus total cost to download 30 songs is $ 40.7
Answer:
The answer for part A: If the city is hotter in temperature more people will want the cold refreshing lemonade.
Part B: The line of best fit is a line that will have the same amount of point on each side so you should draw a straight line and then make sure it has the same amount of point on each side. To calculate the slope use Y2-Y1/X2-X1, Y-intercept is the point that intercepts the Y-intercept.
Step-by-step explanation:
Part A: Because if it is hot outside you will sweat more being less hydrated which is why more people would want a drink especially lemonade.
Lol C is the correct answer, just count the amount of circles :)
