One long-distance telephone company offers a plan such that the first 20 minutes costs $.99 and each additional minute costs $.09. Solve an inequality to find the maximum amount of full minutes you can talk for $5.00. At first I got: 5 is greater than or equal to .99+(1.8-.09m...
Hello Can you explain the first equation? distance=V(t-10)+V/2 * 10 Where is this distance coming from for me to be able to solve for V? Also where is the 10 coming from in V(t-10) and V/2*10? My final equation solving for V is : V= 10d / 4(t-10)
