I have attached the graph of y = -x + 1.5
The line goes through the points (0,1.5) and (1.5,0)
The first thing you have to do is know the equation. The equation is a(1+p)^t.
a= the amount of money p= the percent represented as a decimal and t=time ( the t is raised as an exponent)
so, in this case, it is represented as 200(1+0.05)^2\
200(1.05)^2
200(1.1025)
220.5 That is how much extra he would owe in interest fee's
is an expression. And an expression is like an equation except that it has no "sides". Expression is something after being solved gives the answer. An equation on the other hand, shows something being equal to something else.
