The price of a new car is $29,990 if the sales tax rate is 6.5% then how much sales tex is being charged? what is the totall cost for the car including tax?

Sales tax= $1,949.35

Total cost of the car including tax= $31,939.35

Step-by-step explanation:

sales tax = 0.065 x $29,990 = $1,949.35

Total cost of the car= car's price + sales tax

Total cost of the car= $29,990 + $1,949.35

Total cost of the car= $31,939.35

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
