<span>I am detailing it to show you how to calculate an explicite equation
Arithmetic Progression First term 7 , second 3 hence d=3-7 = - 4</span>
n=Term rank ==>║ 1 2 3 4 5 6 7......n
Value ====>║ 7 3 -1 -5 -9 -13 -17.......
a(n) (sub Notation║ a₁ a₂ a₃ a₄ a₅ a₆ a₇.....a(n)
Term 1 = a₁ = 7........................7-4(0)
Term 2 = a₂ = 3........................7-4(1)
Term 3 = a₃ = -1.......................7-4(2)
Term 4 = a₄ = -5.......................7-4(3)
Term 5 = a₅ = -9.......................7-4(4)
Term n = a(n) ============7-4(n-1)
So A. an = 7 − 4(n − 1); all integers where n ≥ 1
Answer:
n= 85/12
Step-by-step explanation:
Solve by distributing then simplify the arithmetic
it will be 12n - 75 = 13
Add 75 to both sides then Simplify the arithmetic
It will be 12n = 13 + 72 which is 12n = 85
Divide both sides by 12 then Simplify the fraction
it will be like that
12n/12 = 85 / 12
which will equal n = 85/12

Answer:
$20
Step-by-step explanation:
We are given the percentages of how much she spent on each purchase but we need the percentage of what is left after each purchase. We calculate this by subtracting each percentage from 100% like so.
100% - 40% = 60%
100% - 20% = 80%
100% - 50% = 50%
Next we need to do is change the percentages into decimal format. We do this by moving the decimal 2 digits to the left. Therefore the percentages wasted are the following
60.0% ⇔ 0.60
80.0% ⇔ 0.80
50.0% ⇔ 0.50
Now that we have the percentages in decimal format we can calculate the total price (t) by retracing the spending process. The spending process was following.
So we have to retrace by solving for , then , and finally (t)
... divide both sides by 0.50
.... divide both sides by 0.20
.... divide both sides by 0.60
Finally we can see that the Total amount of money that Alice had before lunch was $20
