A parent volunteer group is raising money by making custom hats to sell at school activities. They plan to sell the hats for $12. Each hat costs $6 to

make. They spent $50 for advertising.

Use n to represent the number of hats they sell. Multiply this by the money

they make for each hat, then subtract the advertising cost.

Which expression represents the money that the group raises?

A. 12n - 6 - 50

O B. 50 - (12 – 6) n

O C. (12 - 6)n - 50

O D. 12 - 6n - 50

B

Step-by-step explanation:

The answer is B because you minus 50 from 12 and 6.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
