Answer:
d = 3(h - 2)
Step-by-step explanation:
h = d/3 + 2
taking 2 to the right hand side
h - 2 = d/3
multiplying both sides by 3
3(h - 2) = d
therefore
d = 3(h - 2)
Answer:
Part A: 272 teenagers surveyed like hard rock.
Part B: 200 is the total number of teenagers that Damian surveyed.
Part C: Polly surveyed 850 teenagers to find out their favorite type of music. She found that 132% of the teenagers surveyed like hard rock.

32/100 x 850 = 272.
Part B: if Total is T, then 75% of T is = 150, i.e,
75/100 x T = 150, making T subject of relation, then T, Total = 200.
