Don't know in what impoverished Latin America shithole you living in or if your mom is still doing the groceries for you, but food do not cost this little in USA. Spaghetti alone would cost more than 2$ so even 1/4(she having more than that) of pack will be >.50$ , the sauce another 3-7 , unless you make it yourself out of stolen vegetables from neighbors garden. Pre made crap food is cheaper in USA if you go for quantity, still not an excuse to chose quantity over quality
