Jasmyn and her three friends went out for lunch. They decided to leave a 15% tip. The receipt showed a total of $42.98 before tax and tip. The sales tax rate in Pleasantville is 8.75%. Which of the following choices best represents the amount the girls paid for their meal, including tax and tip? Question 2 options: $45.10 $46.74 $53.75 $68.49

$53.75

Step-by-step explanation:

Percentages

Percentages often express quantities related to a reference quantity as parts of one-hundred. For example, 5 as compared to 50 is one part in 10 or 10 parts in 100, i.e. 10%.

When Jasmyn and friends had to pay for the receipt, it showed $42.98. We must add a 15% tip:

42.98*15/100=6.447

the receipt should be for

$42.98+$6.447= $49.43 including the tip. Now for the tax, we must add another 8.75%:

49.43*8.75/100=4.32

Thus the total amount to be paid for the girls is

$49.43+$4.32=$53.75

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
