we know that
In an Arithmetic Sequence the difference between one term and the next is a constant
where
a1 is the first term
d is the common difference between terms
n is the number of months (in this problem)
case a) Mandy
------> equation 
in this equation the first month is April
case b) Bill
-------> equation 
In this equation the first month is May
With the equation and the equation
calculate the attached table
therefore
the answer is
December
Answer:
r = 2
Step-by-step explanation:
2(8r + 5) = 24 + 9r
16r + 10 = 24 + 9r
16r - 9r = 24 - 10
7r = 14
r = 2
Answer:
6 service contracts were sold.
Step-by-step explanation:
A salesperson earned $300 a week plus a bonus of $18 for each service contract sold.
Weekly Salary = 300W + 18X
where W = number of weeks and X = number of service contracts sold.
the pay one week was $408 how many service contracts were sold?
Weekly Salary = $408
W = 1 week
408 = 300(1) + 18X
408 = 300 + 18X
408 - 300 = 18X
108 = 18X
108/18 = X
6 = X
Step-by-step explanation:
d/dx [f(x)]
= d/dx [(2x + 5)⁶]
= 6(2x + 5)⁵ * d/dx (2x + 5)
= 12(2x + 5)⁵.
