Solve the given problem. 1. Mark started selling snacks in the nearby school. In one day he spends P 200 for rent and P 25 for each snack item he prepares. His expenses in a single day can be expressed as the function C(x) = 25x +200, where x is the number of items and C(x) is his daily expenses in pesos. How much are his expenses if he prepares 100 snack items? 2.The function for the height of an object dropped from 100 meter tall platform at time t in seconds is approximated by s(t) = 5t2 + 100.( This formula is based on an approximated value for acceleration g = 10m/s2 due to gravity). A. What is the height of the object after 2 seconds? B. At what time will the object reach 50 meters?​
