Holly, Wei-Kong and Wilfred all get paid the same hourly rate. In one week Holly works for twice as long as Wei-Kong and Wei-Kong works for three times as many
hours and Wilfred.
The total of their wages that week is £850.
Work out how much Holly receives.

Holly = £510

Step-by-step explanation:

Wei-Kong = 3x

Holly = 2(3x) = 6x and

Wilfred = x

3x + 6x + x = 850

10x = 850

x = 850/10

x = 85

Holly = 6(85)= 510

Holly receives £510.

Step-by-step explanation:

Assuming you made a typo and meant "Wei-Kong works for three times as many hours AS Wilfred:

Wilfred= x

Wei-Kong= 3x (because he works three times as long as Wilfred)

Holly= 6x (because she works twice as long as Wei-Kong)

The question asks for the total of their wages.

x + 3x + 6x = 850

10x = 850

x = 85

This is not the final answer. Substitute this value for X into the equation above for Holly:

Holly = 6x

Holly = (6)(85)

Holly = £510 (final answer)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
