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.)

Hoped I helped!
5/ .5 , if two people splitting it get .25 each and 4 people splitting it get 1/8 (.125) 5 people would be about 1/16 which is 0.0625 in decimal terms
Answer:
6%
Step-by-step explanation:
Interest = Principal x Rate x Time (in years)
30 = 500r
r = 3/50 or 6/100 which is 6%
If you add them straight down:
2d-e = 7
d + e = 5
Then the e's cancel out.
You are left with 3d = 12
Then solve for d by dividing each side by 3.
Now you have d =4.
To solve for e go back into one of your original equations and substitute 4 for the d.
You can use either equation, so I'll choose the second one.
4 + e = 5
Now solve for e by subtracting each side by 4.
Now you have e = 1.
So your solutions are d = 4 and e = 1
