Jennifer edwards can subscribe to a newspaper for $99 for a year, $67 for eight months, $38 for four months, or $0.30 per day. w
mylen [45]

There are some kinds of subscription to a newspaper given. We have to find which is the best buy for it. We will find each subscription for a year and check which one is the lowest.

$99 for a year.

$67 for 8 months.

So for 1 month we will get by dividing it by 8.

We know that there are 12 months in a year.

So for 1 month = $67/8 = $8.375.

For 12 months = $(8.375)×12 = $100.5

So when the subscription is $67 for 8 months, it will take $100.5 for a year.

$38 for 4 months.

For 1 month = $38/4 = $9.5

For 12 months = $(9.5)×12 = $114

So when the subscription is $38 for 4 months, it is $114 for a year.

$0.30 per day.

We know that there are 365 days in a year.

So for 1 day = $0.30

For 365 days = $(0.30) × 365 = $109.5

So when the subscription is $0.30 per day, it is $109.5 for a year.

So the lowest is $99 for a year.

So we can say $99 for a year is the best buy.

QUESTION 2 Write the slope-intercept form of the equation of the line through the gran point micia the grea slope through: (5,-2
Lubov Fominskaja [6]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -1x +b

Using the point for x and y we can calculate b

-2 = -1(5)+b

-2 = -5+b

Add 5 to each side

-2+5 = b

3 = b

y = -x+3

Nathan, a tutor, buys 5 calculators for $7.50 each at a store, planning to provide one to each of his clients. However, the next
harkovskaia [24]

Answer: 5 (7.50-3 )

Step-by-step explanation:

Given: Previous price of calculator = $7.50

Number of client =5

Total price = (Number of calculators) x (Price for each calculator)

Total price of 5 calculators = (5 x $7.50)

New price of calculator = $5.00

Number of client =3

Total price of 3 calculators  = (3 x $5)

Price will receive = (Total price of 5 calculators) -(Total price of 3 calculators  )

= (5 x $7.50) -  (3 x $5)

= 5 (7.50-3 )

Required expression: 5 (7.50-3 )
