At Uriah's coffee shop, the amount of ground coffee beans left in stock on a given days a function of the amount of coffee sold that day. If "c" is the number of cups of coffee sold, and "z(c)" is the number of ounces of ground coffee left in stock, then z(c)=50-c/7. How many cups of coffee will Uriah have sold when he runs out of ground coffee beans?

so you want z(c) = 0

0 = 50 - c/7
c/7 = 50
c = 350
