HELP PLZ NOT good w/ percentage this my ixl hw. Ken buys a rocking chair during the sale. If the original price was $70, how much does Ken pay? (its 30% off)

$21

Step-by-step explanation:

The easiest way of calculating discount is, in this case, to multiply the normal price $70 by 30 then divide it by one hundred. So, the discount is equal to $21.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

unless if u could do my questions, if not i wouldn't want to
