Answer:

2.23

Step-by-step explanation:

0.48 for the first ounce, and then 0.20 for the rest.

0.48 + (0.20 x 3) = 1.08

.95 ounces? We round that to 1.00 ounces.

1.08 + 1 = 2.08 BUT

<em>It's .95, isn't it? We need to do another part. </em>

.95 divided by 0.20 (the ounces by the cost) = 4.75

You need to convert the 4.75 to a fraction, so 4.75 becomes 4 3/4.

subtract the missing amount (to make the fraction equal to 1) from the cost, so

1/4 of 0.20 is 0.5. Subtract 0.5 from 0.20 makes it 0.15.

<em>Finally, add the costs.</em>

2.08 + 0.15 = 2.23.

Helpppppp please !!?

Please refer to my image where it shows my work as I’m explaining.

Okay, for system 1:

1. I am using the elimination method to solve. So I check if all the terms are lined up and if any are the same. I found that 2X are common in both equations.

2. The goal is to “eliminate” the term hence the name. So I can choose to add or subtract. I chose subtraction because 2 - 2 equals 0 which is our goal. Solve for the rest of the terms. This will lead to getting y =4. Refer to image for the work.

3. Last step to to find the X value. We do this by picking any of the given equations,then substitute y with 4 and solve to eventually get x = 10. Refer to image for the work.

FOR SYSTEM 2:

1. Again, I am using the elimination method to solve. I noticed that NONE of the terms are in common so I will have to intervene. You can chose any term to create a match with but I chose Y since it was the one I could use the smallest number to multiply with. When multiplying, DONT just multiply Y, multiply ALL the terms in the equation or else everything will crash.

2. Now that I have terms in common I can choose to add or subtract. I chose subtraction because 2-2 equals zero which is what we want. Solve look at image for my process which lead to X = -8

3. Last step is to find the value of Y. Chose any of the given equations in system 2 then substitute x with -8. Refer to image to see process. It lead to y = 20


To check the validity of the answers, substitute the x and y values into both equations both side of the equal side should have the same number. Hope that helped!
