A.4d+$13.00-$6.00=$13.20 is your answer.
The reason for this is :
Step One : Start with what you know
($13.00-$6.00)
Then make a full equation based on what you need to find out.($7.00+4d)/4=(13.20)/4
Start simplifying.
(1.75+d)-1.75=(3.3)-1.75
Continue to simplify for your answer.
d=1.55
1.55 is the answer.
(A is your answer.)

Answer:
Step-by-step explanation:
Their original price was 3.50, meaning that 3.50 is 100% of the price. We can find the percentage of the new price, 2.80, by using ratios.
3.50 100%
2.80 x%
x = 100% * 2.80 / 3.50 = 80%
The new price, 2.80, is 80% of the original price. Since 100% - 80% is 20%, this means that the decrease of the price was 20%.

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Slope Formula:
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Point (4, 15)
Point (-1, -15)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:
- Subtract:
- Divide:
<u>Step 3: Find y-intercept </u><em><u>b</u></em>
- Define: y = 6x + b
- Substitute: -15 = 6(-1) + b
- Multiply: -15 = -6 + b
- Isolate <em>b</em>: -9 = b
- Rewrite: b = -9
<u>Step 4: Write linear equation</u>
<em>Substitute in all variables.</em>
y = 6x - 9
And we have our answer!
