X = amount of seeds.
y = amount of dried fruits.
we know the snack mix contains both, and we know is 10oz, thus x + y = 10, whatever ounces "x" and "y" are.
how much is it for "x" ounces if each one costs $1.5? well is just 1.5*x or 1.5x.
how much is it for "y" ounces if each one costs $2.5? well is just 2.5*x or 2.5x.
the mix contains 10 ounces, each of which costs $2.2 each, how much will it be then for 10 oz? well, is just 10 * 2.2, or $22.
since the whole 10 oz snack mix costs 22 bucks, then 1.5x + 2.5y = 22.
how many ounces of dried fruit is there anyway? well, y = 10 - x.
y = amount of dried fruits.
