The amount of sales tax on a new car varies directly to the purchase price of the car. if a $25000 car pays 1750 in sales taxes, what’s the purchase price of a new car with 3500$ in sales tax ?

50000

Step-by-step explanation:

$25000 car pays 1750 in sales taxes

P x CP = ST

P is the percentage, CP is the price of the car, and ST is the Sales Tax

P x 25000 = 1750

P = 1750/25000

P = 0.07 x 100

P = 7%

what’s the purchase price of a new car with 3500$ in sales tax ?

P x CP = ST

7 x CP = 3500

CP = 50000

The drum capacity is 180 liters.

Step-by-step explanation:

Let the capacity of the drum be c.  Then the contents of the drum at the beginning are (3/4)c, and

if 30 liters are drawn out, then the contents are (3/4)c - 30 liters = (7/12)c.

Here the LCD is 12, and so we have (9/12)c - (7/12)c = 30 liters, or

(2/12)c = 30 liters, or c = (12/2)(30 liters) = 180 liters

The drum capacity is 180 liters.
