Lee wanted to compute the monthly payment on a 2-year, $8,400 loan at an
apr of 3.07%. she entered the keystrokes at the right on her calculator. the
display gives an answer of 48, which lee knows is incorrect. explain what her
error was.
8400 (0.0307/12) (1+0.0307/12)^24/(1+0.0307/12)^24-1 1

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

40% off the regular price is the correct answer.
