Answer:
287 students were eligible for the discount :)
Step-by-step explanation:
★ Arithmetic Progression [ Explicit and Recursive notation ] ★
Arithmetic Sequence - 19 , 9 , -1 ...
Recursive Notation -
First term = 19
Common difference = -10
In subscript notation - [ a₁ = 19 , aₙ = aₙ-₁ -10 ]
In functional notation - f(n) = f (n -1) -10
Explicit Notation - f ( n ) = f ( 1 ) + d ( n - 1 )
= 19 - 10 ( n -1 )
= 29 - 10n
It's functional and subscript notations resides the same
Answer:
5
Step-by-step explanation:
Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d
Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d
Divide 1.25 from both sides. You get 5 = d
C=20m+15 represents the relationship between cost and number of months.
Step-by-step explanation:
Given,
Initial fee charged by gym = $15
Per month fee of gym = $20
Let,
m be the number of months.
C be the total cost for m months.
Total cost = Initial fee + Per month fee*number of months
C = 15+20m
C=20m+15
C=20m+15 represents the relationship between cost and number of months.
