Answer:
Number of days = 3
Step-by-step explanation:
Let
x = number of days
Rebound game rental = 4 + 2x
Girl right game center = 1 + 3x
Equate both rental companies to find x
Rebound game rental = Girl right game center
4 + 2x = 1 + 3x
Collect like terms
4 - 1 = 3x - 2x
3 = x
x = 3 days
Number of days = 3
A^2 + b^2 = c^2
7^2 + 4^2 = 65
square root of 65 is 8.06
answer: 8.06
To solve for the A or the principal amount plus interest you can use two formulas:
A = P + I
Where: P = Principal
I = Interest
or you can use
A = P (1+ rt)
Where: P = principal
r = rate in decimal
t = time in years
With your given you can use the second one, without having to use the first.
Given that the Principal amount is $222 and the rate is 12% and time is 10 years, we first need to convert your rate into decimal by dividing the value in percent by 100 which will yield 0.12.
Then now we can just input the data that you know into the formula:
A = P(1+ rt)
= $222(1 + (0.12)(10))
= $222(2.2)
= $488.40
Your A is then equal to $488.40
If you need to get the simple interest all you need to use is the first formula given:
A = P + I
for the interest you transpose the P to the side of the A and you will get:
I = A - P
= $488.40 - $222
= $266.40
$266.40 is the added interest to the principal amount.

Answer:
Step-by-step explanation:
The sale price is out of the original price so do 424.15 / 499.00 to find what it is out of in decimal form. Multiply your answer by 100 to find the percentage.
So:
424.15 / 499.00 =0.85
0.85 x 100 = 85
So the answer would 85%.
Hope this helps!
