danielle bought a fountain online. it cost $531 plus 25.1% shipping and handling. what was the total cost?

round your answer to the nearest cent

The total cost of the fountain, including shipping and handling was US$ 664.28

Step-by-step explanation:

1. Let's check the information given to resolve the question:

Cost of  the fountain purchased by Danielle =  US$ 531

Additional shipping and handling costs  = 25.1%

Total cost =  x

2. Replacing with the values:

Total cost  = Cost of  the fountain purchased by Danielle * Cost of  the fountain purchased by Danielle

Total cost  = 531 + 25.1% (531)

Total cost  = 531 + 0.251 * 531

Total cost = 531 + 133.28

Total cost = US$ 664.28

Danielle bought a fountain online ,the total cost price paid is $664.281 or $664.28 (rounded to nearest cent)

Explanation:

Given the cost of the fountain is $531

Shipping and Handling charges = 25.1% of $531

25.1% of $531  = =133.281

Total cost price = cost of fountain +  Shipping and Handling charges

                          =531 + 133.281

                          = $664.281

Therefore, the total cost price paid is $664.281 or $664.28 (rounded to nearest cent)

We can solve these equations by using substitution method where you substitute one equation to the other and solve for the value of the other variable. We do as follows:

y = 2x^2
y = –3x −1

 2x^2 = –3x −1
 2x^2 +3x +1 = 0

x1= -0.5
x2 = -1
y1 = 0.5
y2 = 2
