If the value depreciates 8.6%, it is 91.4% of what it was the year before. The value can be modeled by
y = 19500(0.914)^x
If you divide 537 in to 12 groups. each group would have 44 cookies and you would have 9 left.
Answer:
Step-by-step explanation:
<u>Let the price before tax be x, then we have:</u>
- x + 8% = 372.60
- x + 0.08x = 372.60
- 1.08x = 372.60
- x = 372.60 / 1.08
- x = 345
The initial price was $345
Answer:
h = 12
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.75h + 3 = 12
<u>Step 2: Solve for </u><em><u>h</u></em>
- Subtract 3 on both sides: 0.75h = 9
- Divide 0.75 on both sides: h = 12
<u>Step 3: Check</u>
<em>Plug in h into the original equation to verify it's a solution.</em>
- Substitute in <em>h</em>: 0.75(12) + 3 = 12
- Multiply: 9 + 3 = 12
- Add: 12 = 12
Here we see that 12 does indeed equal 12.
∴ h = 12 is a solution of the equation.
