Answer:
or 
.
Step-by-step explanation:
Suppose, the first side is a, the second side is b, and the third side is c. So:
→ a = s - 4
→ b = s
→ c = (s - 4) + 3
→ a + b + c = 15
First step, find the value of s
a + b + c = 15
(s - 4) + s + (s - 4) + 3 = 15
3s - 5 = 15
3s = 15 + 5
3s = 20

So, the third side is
c = (s - 3) + 4
c = s + 1
c =

<h3>What is ratio?</h3>
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given ratio: A: B : C = 5 : 3 :2
let the common ratio be 'x'.
Grade A cost = 5x
Grade B cost = 3x
Grade C cost = 2x
cheapest seats the concert £16
So,
2x=16
x=8
Now, Grade A cost = 5x = 5*8 = £40
Grade B cost = 3x= 3*8 = £24.
