I think it is D, Hope this helps!
8x8x8x8 (St least I think.. I'm not exactly 100% sure.)
Answer:
(-1, 1)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 3x + 4
y = x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: 3x + 4 = x + 2
- Subtract <em>x</em> on both sides: 2x + 4 = 2
- Subtract 4 on both sides: 2x = -2
- Divide both sides by 2: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define: y = x + 2
- Substitute: y = -1 + 2
- Add: y = 1
And we have our answer!
First find 10%
so 17.64/2
= 8.82
then move decimal over one
so $88.2
is the bill
