the original cost of a piano is 19,100 and it is on a sale for 19% off its original price if the total l cost includes a 5% sale

amid [387]

Answer:

16,244.55

Step-by-step explanation:

Original cost of piano = 19,100

19% off on 19,100 = 0.19*19100 = 3,629

Selling cost = 19100 - 3629 = 15471

Sales tax = 5% =0.05

Amount of sales tax = 0.05*15471 = 773.55

Total selling cost of piano = Selling cost + Amount of sales tax = 15471 + 773.55 = 16,244.55

Ben has 50 drinks and paid 2$ for each. What is 67% of the final price ?

Debora [2.8K]

67% of final price is $67.

Step-by-step explanation:

Given,

Number of drinks Ben has = 50

Amount paid for each drink = $2

Amount paid for 50 drinks = 50*2

Amount paid for 50 drinks = final price = $100

67% of final price = $\frac{67}{100}*100$

67% of final price = $\frac{6700}{100}$

67% of final price = $67

67% of final price is $67.

blagie [28]

Answer:

The width of the garden is 7 feet.

Step-by-step explanation:

If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.

Area = width * length

A = wl

Substitute variables.

56 = 8w

Divide by 8.

7 = w, or w = 7.

The width of the garden is 7 feet.
