    Answer:

    12 hr. mowing lawns

    28 hr. working at Mc Donalds

    Step-by-step explanation:

    Let t = time mowing lawns

    then 40 – t = time working at McDonalds

    7,5(40 – t) + 6t = 282

    300 – 7.5t + 6t = 282

    -1.5t = -18

    t = 12 hr. mowing lawns

    40 – t = 40 – 12 = 28 hr. working at Mc Donalds
