    The following statements are true;

    The expression 23h represents the total charge for  Elegance Home Painting.

    If José hires the painters for 10 hours, then Elegance  Home Painting will be cheaper.

    If José hires the painters for 20 hours, then Krystal Klean  Painting will be cheaper.

    Step-by-step explanation:

    Given,

    Amount charged by Krystal Klean painting to come out = $175.00

    Per 30 minutes charges = $7

    1 hour charges would be $14.

    Let,

    h be the number of hours.

    Total cost for Krystal Klean = 14h + 175

    Amount charged by Elegance per hour = $23

    Total cost = 23h

    The expression 23h represents the total charge for  Elegance Home Painting.

    As Jose will choose from both painters, therefore, he will only hire one.

    For 10 hours;

    h = 10

    Krystal Klean;

    Total charges = 175 + 14(10)

    Total charges = 175 + 140 = $315

    Elegance Home;

    Total charges = 23(10) = $230

    If José hires the painters for 10 hours, then Elegance  Home Painting will be cheaper.

    For 20 hours;

    h = 20

    Krytal Klean,

    Total charges = 175 + 14(20) = $455

    Elegance Home = 23(20) = $460

    If José hires the painters for 20 hours, then Krystal Klean  Painting will be cheaper.
