a)From the information given, x is the number of pounds of caramels included in the box and y is the number of pounds of truffles in the box. The given equations are
x + y = 3
8x + 12y + 1 = 30
The pounds of candy in the box is x + y = 3. Thus, there are 3 pounds of candy in the box.
b) Since x represents the number of pounds of caramels and equation 2 represents total cost, then, the price per pound of caramels is $8
c) 12y represents the the cost of y pounds of truffles.
d) 8x + 12y + 1 in the second equation represents
Cost of x pounds of caramels + cost of y pounds of truffles + cost of box = $30
