    y = 23.4 hrs

    Step-by-step explanation:

    y$12.35 = $289

    y = hours he'll to work

    $12.35 = amount earned per hour

    $289 = cost of the iPhone

    Therefore

    y12.35 = 289

    Divide both sides by 12.35

    y12.35/12.35 = 289/12.35

    y = 23.4

    y = 23.4 hrs

    Fredrick will have to work for 23.4 hrs to get $289 for the phone

    Check

    23.4 x 12.35 = 288.99

    = 289

    25 HOURS

    Step-by-step explanation:

    12.35 (x) ≥ 289

    12.35 (20) ≥ 289

    247≥289 NO FOR 20

    12.35 (25) ≥ 289

    308.75≥289 YES FOR 25 HOURS
