    inequalities

    Marcus can spend no more than $120 on jeans and shirts for school. He buys 3 pairs of jeans at $32 each. If x represents the dollar amount he can spend on shirts, which of the following inequalities could be used to determine the possible values for x ?



    (A) (3) x 32- x 120
    (B) (3) x 32- x 120
    (C) (3) x 32+x 120
    (D) (3) x 32+ x 120
    (E) x (3) x 32

    since he can spend no more than $120, that means that he can spend $120 or less than that.

    the first spend is \$3\times32 and the last is x, so the total amount is 3\times32+x which can not exceed but it can be equal to \$120, hence our inequality is 3\times32+x\le120.
