How many multiples of $6$ are between $100$ and $500$?

lapo4ka [179]

ANSWER

EXPLANATION

This will form a sequence with first term:

$a_{1} = 102$

with constant difference d=6 and last term

$l = 486$

The last term is a term in the sequence, therefore;

$l=a_1+d(n-1)$

$486=102+6(n-1)$

$486 - 102 = 6(n-1)$

Simplify the LHS

$384= 6(n-1)$

Divide both sides by 6.

$64=n-1$

$64 + 1 = n$

Therefore

$n = 65$

Hence there are 65 multiples of 6.

In 1999 the minimum wage for adults was £3.60 per hour.

Black_prince [1.1K]

Answer:

75.3% (1 d.p.)

Step-by-step explanation:

<u>Percentage Change</u>

$\sf percentage\:change=\dfrac{final\:value-initial\:value}{initial\:value} \times 100$

Given:

initial value = £3.60
final value = £6.31

$\begin{aligned}\implies \sf percentage\:change & =\dfrac{6.31-3.60}{3.60} \times 100\\\\& = \dfrac{2.71}{3.60} \times 100\\\\& = 75.277777... \%\end{aligned}$

Therefore, the percentage increase in the minimum wage was:

75.3% (1 d.p.)
