Lucy spent $165 in December using a new credit card. In January, she began paying between $15 and $25 each month towards her acc
ount balance. The equation f(x) = 165(0.8)x describes the curve of best fit for Lucy's account balance f(x). Let x represent the number of months since December. Month Account Balance December $165.00 January $132.00 February $105.60 March $84.48 Using the equation for the curve of best fit, what will Lucy's account balance be in June? Round to the nearest cent. A. $28.25 B. $53.95 C. $43.25 D. $33.25
