If 90 students were surveyed and 50 said they would buy a wristband, how many wristbands should monty order for the school of 1800 students?

He should buy 1000 wristbands.

Since 50/90 students said they would buy a wristband, we can set up this proportion.

multiply 50 * 1800 divided by 90 = 1000

(3x-8) or (3x+8)

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
