WHICH ONE IS NOT PROPORTIONAL PLEASE HELP

Mechanical pencils are sold in a package of 4 pencils for $3.52. Which statement is not proportional to this?

a single pencil for $0.88

two packages of 4 pencils for $7.04

Buy one package, get the second 50% off.

One small package, containing 2 pencils, costs $1.76.

Buy one package, get the second 50% off is proportional.

Step-by-step explanation:

4 divided by 3.52 is .88, so that is the base amount.

We know that a single pencil is .88, so that is right.

To find two packages, you would multiply one package by 2 (3.52 x 2)

To find the price of two pencils, you multiply the price of one pencil by two (.88 x 2) but is 1.76

The only one that does not fit is the buy one get one 50% off.

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!

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
