The cost (in dollars) of making n birthday cakes is represented by C = 24n + 35. How many birthday cakes are make when the cost is $395? Explain your reasoning.
so C = $395. you would write it out like 395 = 24n + 35 subtract the 35 from both sides to get 360 = 24n divide 24 on both sides to get 15. n = the number of cakes made, which is 15
