The total cost is given by the equation:
C(t) = 45 + 25(h-1) where h is the number of hours worked.
We can check for each option in turn:
Option A:
Inequality 5 < x ≤ 6 means the hour is between 5 hours (not inclusive) to 6 hours (inclusive)
Let's take the number of hours = 5
C(5) = 45 + (5-1)×25 = 145
Let's take the number of hours = 6
Then substitute into C(6) = 45 + (6-1)×25 = 170
We can't take 145 because the value '5' was not inclusive.
Option B:
The inequality is 6 < x ≤ 7
We take number of hours = 6
C(6) = 25(6-1) + 45 = 170
We take number of hours = 7
Then C(7) = 25(7-1) + 45 = 195
Option C:
The inequality is 5 < x ≤ 6
Take the number of hours = 5
C(5) = 25(5-1) + 45 = 145
Take the number of hours = 6
C(6) = 25(6-1) + 45 = 170
We can't take the value 145 as '5' was not inclusive in the range, but we can take 170
Option D:
6 < x ≤ 7
25(6-1) + 45 < C(t) ≤ 25(7-1) + 45
170 < C(t) ≤ 195

Answer:
6
Step-by-step explanation:
We are doing unit rate.
Unit rate is when you get the value for 1 of the variables. In this, we would want to get the value for t. We do
to find the t value. Now we do
to find the value of the missing t. T=6.

Answer:
The numbers of grooming visits for which James and Bradly would charge the same amount is 2
Step-by-step explanation:
Let
w -----> the numbers of grooming visits
y ----> the charge in dollars
we know that
<em>James</em>
----> equation A
<em>Bradly</em>
----> equation B
equate equation A and equation B

Solve for w



therefore
The numbers of grooming visits for which James and Bradly would charge the same amount is 2
