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
28% is 28/100 as a fraction but the simplest form is 14/50 and it can be simplified to 7/25. the decimal is 0.28
fraction is 7/25
decimal is 0.28

Answer:
37/6
Step-by-step explanation:
Simplify the following:
(12 + 1/3)/2
Put 12 + 1/3 over the common denominator 3. 12 + 1/3 = (3×12)/3 + 1/3:
((3×12)/3 + 1/3)/2
3×12 = 36:
(36/3 + 1/3)/2
36/3 + 1/3 = (36 + 1)/3:
((36 + 1)/3)/2
36 + 1 = 37:
(37/3)/2
37/3×1/2 = 37/(3×2):
37/(3×2)
3×2 = 6:
Answer: 37/6
