Mario goes shopping

Probability Level 2

Mario needs a new suit, consisting of pants and a jacket. The first store he visits sells $4$ pants and $3$ jackets. The second store he visits sells $7$ pants and $9$ jackets. The third store he visits sells $6$ pants and $12$ jackets. If Mario is willing to get his pants and jacket at different stores or at the same store, how many different pant/jacket combinations can he buy?
