Answer:
Unit Rate of Change = 1.27%
Step-by-step explanation:
In 2000, t=1 and Total Music sales = 24.8%
In 2007, t=7 and Total Music sales = 32.4%
The Slope 
The Unit Rate of Change is 1.27% and it means that the Total Music Sales Increased by approximately 1.27% every year.
Answer:
74.30
Step-by-step explanation:
Let s = entry price for a student
Let t = entry price for a teacher
4s +5t = 95
6s+10t = 173
I will use elimination to solve this problem.
Multiply the first equation by -2
-2(4s +5t) = -2*95
Distribute
-8s - 10t = -190
Add this equation to the second equation to eliminate t
-8s - 10t = -190
6s+10t = 173
----------------------
-2s = -17
Divide by -2
-2s/-2 = -17/-2
s = 8.50
Now we need to find t
4s +5t = 95
Substitute s=8.50
4(8.50) +5(t) = 95
34 +5t = 95
Subtract 34 from each side
34-34 +5t = 95-34
5t = 61
Divide by 5
5t/5 = 61/5
t = 12.20
We want to find the cost for 3 students and 4 teachers
3s+4t
3(8.50) + 4(12.20)
25.50 + 48.80
74.30
Answer:
B is the answer
Step-by-step explanation:
because if you multiply 8 times 17 you will get the answer! hope this helped!!!!
Know: 17.35 is equivalent to 4 burgers 3 med fries
6.09 Is equivalent to 1 burger med fries
9.34 8s equivalent to 2 burgers med fries and med drink
So what you want to do is take 6.09 and subtract it from 9.34 which is 3.25. Now 3.25 is your burger price.
What you want to do now is take your 3.25 and multiply it by 4 which would be 13. 17.35 subtract 13 would be 4.
4 divided by 3 is 1.33 which is now the price of a med fries.
now for the drink. 3.25 plus 1.33 is 4.58.
6.09 subtract 4.58 is 1.51
Now you have 3.25 as your burger
1.33 as your fries
1.52 for your drink
