    10

    Step-by-step explanation:

    "three times r" = 3r

    "three times r minus ten" = 3r - 10

    "product of 5 and the difference of three times r minus ten"

    = 5 (3r - 10)

    given that r = 4,

    the expression becomes

    5 (3r - 10)

    = 5 [3 (4) - 10]

    = 5 [12 - 10]

    = 5 (2)

    = 10
