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 (
), in sterling pounds per hour, of the line for the first 20 hours worked, that is:
(1)
Where:
- Change in hours worked, in hours.
- Change in pay, in sterling pounds.
If we know that 
and 
, then the basic rate is:
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 
and 
, then the higher rate is:
The higher rate of pay is 10 sterling pounds per hour.
5.82% = 0.0582 in decimal form.

Formula
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
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.
Answer:
n = -12/11
Step-by-step explanation:
4n = -7n - 12
4n + 7n = -7n - 12+7n
11n = -12
11n/11 = -12/11
