Assume that during 2020, Cypress Semiconductor Corporation reported net cash provided by operating activities of $155,215,000, net cash used in investing activities of $207,625,000 (including cash spent for plant assets of $132,370,000), and net cash used in financing activities of $33,365,000. Dividends of $4,460,000 were paid. Calculate free cash flow. (Enter a negative amount using either a negative sign preceding the number e.g. -15,000 or parentheses e.g. (15,000).)
