7. production a glass blower can form 8 simple vases or 2 elaborate vases in an hour. in a
work shift of no more than 8 hours, the worker must form at least 40 vases.
a. lets represent the hours forming simple vases and e the hours forming elaborate vases.
write a system of inequalities involving the time spent on each type of vase.
b. if the glass blower makes a profit of $30 per hour worked on the simple vases and $35
per hour worked on the elaborate vases, write a function for the total profit on the vases.
c. find the number of hours the worker should spend on each type of vase to maximize
profit. what is that profit?

a) ,

b)

c) x = 4, y = 4  , $ 260

Step-by-step explanation:

a)Let, the glass bowler works for x hours on simple vases and y hours on elaborate vases.

According to the question,

-----------(1)

Also, the glass blower has to make at least 40 vases in 8 hours.

So,  

⇒

⇒ ---------(1)

⇒

⇒----------(2)

b)Again profit of the glass blower, ( in $)

 =

= --------------(2)

which will be maximum when x is minimum which is 4 (from (1))

so

and the profit is,

(in $)

=$ 260

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
