Start with the marked-up price to determine the mixture original price, and then look for the quantities of the dried fruit and granola.

T%2A1.25=1.75, using T for the mixture price BEFORE mark-up.
T=1.75%2F1.25
T=1.40 dollars per pound, again this is BEFORE mark-up.

Let u= pounds of granola
Let v = pounds of dried fruit

highlight_green%28%281%2Au%2B2%2Av%29%2FM=1.40%29, and you could just as well say M = 1 pound or 100 pounds, whatever is convenient, BECAUSE NO INDICATION OF HOW MUCH TRAIL MIX WAS MADE! M is the pounds of the mixture. All you can do is find the ratio of v and u. You decide how to go from here.
