Do 200/14 and get 14.2857142857 so about 14 boxes
Do a proportion
8/100= x/70
Cross multiply and divide
70 x 8= 560
560 divided by 100= 5.6
Answer is 5.6
You also could have done .08 x 70 which is also 5.6
Here is you're answer:
Remember you're subtracting integers so remember to use KCC. (Keep, Change, Change)
Therefore you're answer is "-39."
Hope this helps!
Answer:

General Formulas and Concepts:
<u>Pre-Algebra</u>
Order of Operations: BPEMDAS
- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
<u>Algebra I</u>
- Coordinates (x, y)
- Systems of Equations
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
8x + 3y = 20
x + 4y = 17
(1, 4)
<u>Step 2: Check</u>
<em>Plug and verify the coordinates is a solution.</em>
- Substitute in point [1st Equation]: 8(1) + 3(4) = 20
- Multiply: 8 + 12 = 20
- Add: 20 = 20
- Substitute in point [2nd Equation]: 1 + 4(4) = 17
- Multiply: 1 + 16 = 17
- Add: 17 = 17
∴ Since both equations work out, (1, 4) is a solution to the systems of equations.
Okay so start by finding the cost of the sandwich and the drink together. Once you have that number you need to find what 7% (or 0.07) or that number is. HINT it should be less than $0.50. Add this 7% to your sandwich-drink total and ta-da!!!
