PLEASE ANSWER I WILL DO ANYTHING PLEASE

For this question, you need you use the unitary method or proportion. If you apply these ideas to it. You should be able to do this question. Here's my working:

Step-by-step explanation:

25ounces = $3.49

**You need to find what's the price of one ounce**

So assume it like this:

1 ounce = $X

To solve for X, you figure out how did 25 became 1. In this case, it has been divided by 25. So you do the same thing on the other side: Which is $3.49 ÷25 = 0.1396 (Price per ounce for choice A)

Choice B workings:

You apply the same method, so it's 4.79 ÷ 45 = 0.1064444444444 (Price per ounce for Choice B)

So in conclusion, Choice B is cheaper.

**Please note that I'm not a maths teacher, please double check your answer, my answer might be incorrect**

Hope it helps!

Cheers! :)

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
