But the problem asked for the solution set for x^2 - 8x = 24, which is an equation, though not in standard form. And it isn't factorable over the integers. The solution given by the blogger is correct.

In the equation, y= A(1+...Yeah, it has to be 1.7%. In the equation, y= A(1+r)^t, the rate has to be converted to a decimal, and 1.7% is converted to the 0.017 in 1.017. So, subsitution in the equation above would be y= 1350 (1+0.017)^t, which ultimately leads to the original equation given to us in the problem of V(t) = 1350 (1.017)^t. I had taken this test on Wednesday, too, and this question in particular took awhile for me to figure out.
