The cost of other seats £40 and £24.
<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.

Hello from MrBillDoesMath!
Answer:
35
Discussion:
Parallel lines cut by a transversal has corresponding angles equal. . So the corresponding angles x and (3x-70) are equal. That is,
x = 3x - 70 => add 70 to both sides
x + 70 = 3x => subtract x from both sides
70 = 3x - x = 2x => divide both sides by 2
x = 70/2 = 35
which is the third choice
Thank you,
