PLEASE HELP ASAP!!!!
Naily [24]

Answer:

2

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

let

log_{2} 8 = n ⇒ 8 = 2^{n} , that is

2³ = 2^{n} ( equate exponents )

n = 3

and let

log_{3} ( \frac{1}{3} ) = n ⇒ \frac{1}{3} = 3^{n} , that is

3^{-1} = 3^{n} ( equate exponents )

n = - 1

then

log_{2} 8 + log_{3} (\frac{1}{3} )

= 3 + (- 1)

= 3 - 1

= 2

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.
Sladkaya [172]

Answer:

The most cost effective company will be Painting USA that charge $700 to paint Paul house .

As given

Paul is going to have the exterior of his home painted.

Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor.

If it takes 25 hours to paint Paul’s house.

Total amount charge by Painting USA = Painting USA charges for come out  and evaluate the house + Cost of per hour of labor × Total hours take to paint Paul house .

Total amount charge by Painting USA = 75 + 25 × 25

                                                               = 75 + 625

                                                               = $ 700

As given

Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.

Total amount charge by Upscale Home Painting = Cost of per hour of labor × Total hours take to paint Paul house

                                                                                = 40 × 25

                                                                                = $ 1000

Therefore  the most cost effective company will be Painting USA  that charge $700 to paint Paul house .
