The number 42 is increased to 46. what is the percentage by which the number was increased?
Arte-miy333 [17]

Answer:

9.52% ( to 2 dec. places )

Step-by-step explanation:

Calculate the percentage increase using

percent increase = \frac{increase}{original} × 100%

increase = 46 - 42 = 4, hence

percent increase = \frac{4}{42} × 100% ≠ 9.52%

If a ∝ b and a = 18 when b = 3, then find a when b = 5.
Elden [556K]

"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that

a = kb

We're given that a = 18 and b = 3, so that

18 = 3k   ⇒   k = 6

Then when b = 5, we would have

a = 6 × 5 = 30
