Question 1171916: if someone buy a dozen of cakes. The small cakes cost 1,75$ each and the big ones cost each 3,85 with taxes included. And you paid 31,50$ in total. how many cakes did you bought Answer by ikleyn(52781) (Show Source):
If B is the number of big cakes, then the number of small cakes is (12-B).
You then write the total money equation
1.75*(12-B) + 3.85*B = 31.50 dollars.
From the equation
B = = 5.
ANSWER. 5 big cakes and 12-5 = 7 small cakes.
