Joey borrows $2,400 from his grandfather and pays the money back in monthly payments of $200. a. Write a linear function that represents the remaining money owed L(x) after x months. b. Evaluate L(10) and interpret the meaning in the context of this problem.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

$320 to $405

step by step explanation:

in one day he earns between $64 and $81
