100% = 1
75% = 0.75 = 3/4

3/4x = 84     | *4
3x = 336      |  /3
x = 112 

Or you can do like this:
3/4x = 84     |    /3

1/4x = 28

3/4x + 1/4x = 84 + 24
4/4x = 112
x = 112

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

                                                               = $ 700

                                                                                = $ 1000

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

Alexxandr [17]

Answer: 1 ⁸/₂₁ litres

Step-by-step explanation:

First find a common multiple to enable you add them up:

= 21

21 will be the denominator.

Multiply each numerator by the number you get when you divide 21 by the denominator.

= 21/3 = 7

= 7 * 2 = 14

= 21/7 = 3

= 3 * 5

= 15

= \frac{14 + 15}{21} \\\\= \frac{29}{21}

= 1\frac{8}{21} litres
