Answer: y = 20x+75
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost (y) must be equal to the product of the cost per hour of installation (20) and the number of hours that it takes (x); plus the fixed cost of parts and installation (75).
Mathematically speaking:
y = 20x+75

Answer:
a = 15
Step-by-step explanation:
This is your given:
You are going to want to get a alone to get what a equals.
Multiply 3 on both sides to get the a alone
This is a geometric sequence with a common ratio of 2
an = a1 * r^(n - 1)
n = term to find = 21
a1 = first term = 0.05
r = common ratio = 2
now we sub
a21 = 0.05 * 2^(21 - 1)
a21 = 0.05 * 2^20
a21 = 0.05 * 1048576
a21 = 52428.80 <==== after working 21 days
