Blair’s family is eating dinner at a local restaurant. the bill for the food is $79.95. the local sales tax is 6.5%. how much will blair’s family pay in taxes? the service at the restaurant was exceptional, and blair’s mother wants to leave their server a 20% tip. how much tip will be paid?

Original amount x ()

79.95 x () = 5.2

79.95 x () = 15.99

$ 5.20  will be paid as tax.

$15.99 will be paid as tip.

Step-by-step explanation:

Given : Restaurant bill = $79.95.

Local sales tax = 6.5%=0.065  [we divide percentage by 100 to convert it into decimal or fraction]

Tax amount = (Local sales tax) x (Restaurant bill )

= (0.065)x ( $79.95)

= $ 5.19675 ≈ $ 5.20  [ approx]

Hence, $ 5.20  will be paid as tax.

Tip Percentage = 20%= 0.20

Tip amount = (Tip percentage) x (Restaurant bill )

= (0.20) x ($79.95)

=$15.99

Hence, $15.99 will be paid as tip.

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.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
