The given P=15250
<span>r=7.5/100=0.075 </span>
<span>t=x </span>
<span>y = 15250*(1 - 0.075)^x </span>
<span>after 8 years we would have </span>
<span>x = 8 </span>
<span>y = 15250*(1 - 0.075)^8 </span>
<span>y = $8,173.42 </span>
<span>after 8 years the value of the car would be $8,173.42</span>
Ok, first of all, it is important to understand that this function would depend on 2 variables; the number of dollars (x) and the number of pennies (y). Every dollar is equivalent to 100 pennies. So, if we are given x dollars, we have 100*x pennies. If we also have y pennies, we still get y pennies. We need to add these two to get the total amount of pennies. Thus, the correct function is:
f(x,y)=100*x+y
