A car company has found that there is a linear relationship between the money it spends on advertising and the number of cars it

Sveta_85 [38]

Answer:

The required formula for y, the number of cars sold is: $y = 0.008x +200$ .

Step-by-step explanation:

Consider the provided information.

Let x represents the amount of money spend on advertising .

y is number of cars sold,

For each additional 5000 dollars spent, they sold 40 more cars.

$Slope = m = \frac{Rise}{Run}=\frac{40}{5000}=0.008$

The y-intercept form is: $y = mx + b$

Substitute x=60,000, y=680 and m=0.008 in the above equation.

$680= 0.008(60,000)+b$

$b=680-480$

$b=200$

Thus, the required formula for y, the number of cars sold is: $y = 0.008x +200$ .

Duane and Thad plan on retiring 27 years from today and plan to have the same amount saved at that time. In preparation for this

Rzqust [24]

Answer:

Thad deposited an amount of $11,241.58 about 27 years ago,

Step-by-step explanation:

<u>About Duane:</u>

The amount deposited by Duane = $15,000

Time interval = 27 years

Rate = 5.2%

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

$\implies SI = \frac{15,000 \times 27 \times 5.2}{100} = 21,060$

So, the SI on 15,000 after 27 years = $21,060

Now, AMOUNT = PRINCIPAL + SI

= 15,000 + 21,060 = $36,060

Hence, after 27 years, Duane's amount is equivalent to $36,060

<u>Now, About Thad:</u>

Let us assume amount deposited = P

Rate = 6.2%

Time = 27 y

Now, $SI = \frac{P \times 27 \times 6.2}{100} = 1.674 P$

So, the SI on 15,000 after 27 years = $1.674 P

Now, AMOUNT = PRINCIPAL + SI

$36,060 = P + 1.674 P

or, 2.624 P = $36,060

⇒ P = 30,060/2.624 = 11,241.58

Hence, Thad deposited an amount of $11,241.58 about 27 years ago,

Valeria does not charge an initial fee for babysitting but charges $10 an hour. Daniel charges $8 per hour plus an initial fee o

Sloan [31]

Answer:

it depends how many hours both of them make but here is what you can do:

Valeria needs to do 2 hours more than Daniel. This is because Daniel makes $18 and hour and Valeria makes only 10. If you do 10*2 or 10+10 you get 20 which is greater than 18. I hope this helps and good luck!
