The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes)

Ivan

Answer: the remaining credit after 79 minutes of call is $15.52

Step-by-step explanation:

let x represent the number of minutes of call.

Let y represent the remaining credit after x minutes of call.

If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be

Slope, m = (17.2 - 19.84)/(65 - 43)

m = - 2.64/22 = - 0.12

The equation of the straight line can be represented in the slope-intercept form, y = mx + c

Where

c = intercept

m = slope

To determine the intercept, we would substitute x = 65, y = 17.2 and m = - 0.12 into y = mx + c. It becomes

17.2 = - 0.12 × 65 + c

17.2 = - 7.8 + c

c = 17.2 + 7.8

c = 25

The linear function becomes

y = - 0.12x + 25

Therefore, the remaining credit after 79 minutes of call is

y = - 0.12 × 79 + 25

y = - 9.4 + 25

y = 15.52

The value of a professional basketball player's autograph rose 20% in the last year. It is now worth $336.00. What was it worth

sesenic [268]

Answer:

The value of basketball player's autograph a year ago is $280

Step-by-step explanation:

Given as :

The present value of autograph = $ 336.00

The rate of increase of autograph = 20%

The time period = 1 year

Let The value one year ago = $ x

So ,

The value of autograph after n year = The present value × $(1+\frac{Rate}{100})^{n}$

Or, $ 336.00 = $ x × $(1+\frac{20}{100})^{1}$

Or, $ 336.00 = $x × 1.2

∴ x = $\frac{336.00}{1.2}$ = $280

Hence The value of basketball player's autograph a year ago is $280 Answer

Cherry is booking a 3-night stay at a hotel. The rate is $45 per room plus tax.

8_murik_8 [283]

Answer:

The lodging cost of the room is $ 41.28

Step-by-step explanation:

Given as :

The rate of room including taxes = $ 45

The state tax = 6 %

The city tax = 2 %

The municipal tax = 1 %

So, The total tax = 6 % + 2 % + 1 % = 9 %

Let The lodging cost = $ x

So, According to question

x + 9 % of x = $ 45

Or, x + 0.09 × x = 45

Or, 1.09 × x = 45

∴ x = $\frac{45}{1.09}$ = $ 41.28

Hence The lodging cost of the room is $ 41.28 Answer
