Based on the information given, it can be deduced that the initial cost will be $187 and the hourly rate is $72 per hour.
From the information given, the initial cost is $187. The cost for 2 hours is $259 and the cost for 3 hours is $331.
Therefore, the rate per hour will be:
= $259 - $187 = $72
The equation will then be:
= 187 + 72h
Lastly, the difference in the costs is $72.

Answer:
-4, -2, 0, 2
Step-by-step explanation:
the expression for the integers are; x, x +2, x + 4, x + 6
4x + 12 = -4
4x = -16
x = - 4
your integers are; -4, -2, 0, 2
if you add those your answer will be -4
Answer:
Step-by-step explanation:
Let f be a function from N to N.
N_set of all natural numbers
i) one to one but not onto
consider the function
When two numbers have same square we find that the numbers should be the same because they are positive.
So one to one but not onto because consider 3 it does not have square root in N.
ii) Onto but not one to one
Consider
this is onto because every number has a preimage in N.
But not onto because consider 6 and 3, f(6) = 3 and f(3) =3
So not one to one
iii) both onto and one-to-one
f(x) = 
=x+1, x even
This is both one to one and onto since we consider only integers
iv) Neither one to one nor onto
Consider the function
f(x) = 2
This is not onto because 3 cannot have a preimage in N, not one to one because f(1) = f(2) where 1 not equals 2

Hello Grossjoann, if you have 3,500$ with a interest rate of 15.75% at the end of the month you will get 44.10$ below will explain,
Answer:
I = $ 44.10
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 15.75%/100 = 0.1575 per year,
putting time into years for simplicity,
1 months ÷ 12 months/year = 0.08 years,
then, solving our equation
I = 3500 × 0.1575 × 0.08 = 44.1
I = $ 44.10
The simple interest accumulated
on a principal of $ 3,500.00
at a rate of 15.75% per year
for 0.08 years (1 months) is $ 44.10.
