Midnight Margaret’s school notebooks are onsale this month for 20% off regular prices. If apack of 5 notebooks normally costs $1

ch4aika [34]

Explanation:

Discount = 20%

The cost of 5 notebooks = $10

The cost of 1 notebook before applying discount = $10/5 = $2

Applying the discount on the original price:

Discount = $10 × 20% = 10 × 0.20

Discount = $2

The sales price of the 5 notebooks = original price - discount

The sales price of the 5 notebooks = $10 - $2

The sales price of the 5 notebooks = $8

The sales price of 1 notebook = $8/5

The sales price of 1 notebook = $1.6

The amount saved per notebook = The cost of 1 notebook before applying discount -

(10 POINTS ON THIS) Anika is hiking on a rectangular trail at the national park.There are four resting spots along the corners o

nasty-shy [4]

Answer: 10 miles

Explanation:

We define the following resting spots

A = resting spot whose coordinate is (2,2)
B = resting spot whose coordinate is (2,4)
C = resting spot whose coordinate is (5,2)
D = resting spot whose coordinate is (5,4)

If you plot A, B, C, D, you will notice that

(Perimeter of the trail) = 2[(distance from A to C) + (distance from A to B)]

Note that A and C have the same y-coordinates (second number in their ordered pairs), so the distance from A to C is computed as the difference of their x-coordinates (first number in their ordered pairs). Thus,

(distance from A to C) = 5 - 2 = 3

Moreover, A and B have the same x-coordinates and so we compute the distance from A to B as the difference of their y-coordinates. Then,

(distance from A to B) = 4 - 2 = 2

Hence,

(Perimeter of the trail) = 2[(distance from A to C) + (distance from A to B)]
= 2[2 + 3]
= 2(5)
(Perimeter of the trail) = 10 miles
