What type of function represents the relationship between price and number of items sold?

Revenue function is the required function that will represents the relationship between price and quantity sold.

Step-by-step explanation:

Revenue function represents the relationship between price and number of items sold.

As Revenue refers to the total receipt earned from selling the number  of items at a particular price.

Mathematically, it is expressed as

Hence, Revenue function is the required function that will represents the relationship between price and quantity sold.

the solution is 12x-6y

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
