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

Nevermind, the above post has given a full answer.
