In a certain year, brand A of heart-rate watch cost $39.99 and brand B cost $59.99. A nonprofit community health organizatio

Oksi-84 [34.3K]

Answer:

Brand A = 21 heart-rate watches.

Brand B = 13 heart-rate watches.

Step-by-step explanation:

Let A be the number of Brand A heart watches and B be the number of Brand B heart watches.

We have been given that a nonprofit community health organization purchased 34 heart-rate watches for use at a wellness center.

We can represent this information in an equation as:

$A+B=34...(1)$

We have been given that in a certain year, brand A of heart-rate watch cost $39.99 and brand B cost $59.99 and the organization spent $1619.66 for the watches.

We can represent this information in an equation as:

$39.99*A+59.99*B=1619.66...(2)$

We will use substitution method to solve our system of equations.

From equation (1) we will get,

$A=34-B$

Substituting $A=34-B$ in equation(2) we will get,

$39.99*(34-B)+59.99*B=1619.66$

$1359.66-39.99*B+59.99*B=1619.66$

$-39.99*B+59.99*B=1619.66-1359.66$

$20*B=260$

$B=\frac{260}{20}$

$B=13$

Therefore, the organisation purchased 13 heart-rate watches of brand B.

Now let us substitute B=13 in equation (1).

$A+13=34$

$A+13-13=34-13$

$A=21$

Therefore, the organisation purchased 21 heart-rate watches of brand A.

The second option is better

Step-by-step explanation:

Total for the first choice:

8000*5.5/100 + 1500 = $1940

Total for the second choice:

8000*3/100 + 2000 = $2240

As we see the second choice is better as more salary is expected

The equation in slope-intercept form that represents the total fee "y"

to become a member of the library-all-star-members club for "x"

months is y = 2 x + 40

Step-by-step explanation:

The linear in the form of slope-intercept is y = m x + c, where

1. m is the slope of the line

2. c is the y-intercept

Slope of the line represents the monthly fee ⇒ paid every month

y-intercept represents the sign-up fee ⇒ paid once

To become a member of the library-all-star-members club, there is

a $40 sign-up fee and a $2 monthly fee

∵ The monthly fee is $2

∴ m = 2

∵ The sign-up fee is $40

∴ c = 40

∴ The equation is y = 2 x + 40, where y is the total member fee for

x months in the library-all-star-members club

The equation in slope-intercept form that represents the total fee "y"

to become a member of the library-all-star-members club for "x"

months is y = 2 x + 40
