Answer:

a) The basic rate of pay is 6 sterling pounds per hour.

b) The higher rate of pay is 10 sterling pounds per hour.

Step-by-step explanation:

Both segments of the curve are first order polynomials, which means that each have constant slopes.

a) The basic rate of pay is the value of the slope (r), in sterling pounds per hour, of the line for the first 20 hours worked, that is:

r = \frac{\Delta y}{\Delta x} (1)

Where:

\Delta x - Change in hours worked, in hours.

\Delta y - Change in pay, in sterling pounds.

If we know that \Delta x = 20\,h and \Delta y = \pounds\, 120, then the basic rate is:

r = \frac{\Delta y}{\Delta x}

r = \frac{\pounds\,120}{20\,h}

r = 6\,\frac{\pounds}{h}

The basic rate of pay is 6 sterling pounds per hour.

b) By using (1), we calculate the higher rate of pay below. If we know that \Delta x = 10\,h and \Delta y = \pounds \,100, then the higher rate is:

r = \frac{\Delta y}{\Delta x}

r = \frac{\pounds\,100}{10\,h}

r = 10\,\frac{\pounds}{h}

The higher rate of pay is 10 sterling pounds per hour.

Clara Schumann is buying bagels for her coworkers, She buys a dozen bagels priced at $5.49 a dozen. The bakery's cost for making
Tcecarenko [31]

Answer:

The markup rate is 144% .

Step-by-step explanation:

Formula

Mark\ up\ percentage = \frac{(Selling\ price-Cost\ price)\times 100}{Cost\ price}

As given

Clara Schumann is buying bagels for her coworkers, She buys a dozen bagels priced at $5.49 a dozen.

i.e

Selling price of a dozen bagels is $5.49 .

The bakery's cost for making the bagels is $2.25 per dozen.

i.e

Cost price of a dozen bagels is $2.25 .

Putting all the values in the formula

Mark\ up\ percentage = \frac{(5.49-2.25)\times 100}{2.25}

Mark\ up\ percentage = \frac{3.24\times 100}{2.25}

Mark\ up\ percentage = \frac{32400\times 100}{225\times 100}

Mark\ up\ percentage = \frac{32400}{225}

Markup percentage = 144 %

Therefore the markup percentage is 144% .

PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.
