X Company uses account analysis to estimate total overhead costs for each month, with units produced as the activity measure. In May, when production was 1,000 units, the plant manager classified each overhead cost item as fixed and variable as follows: If September production is expected to be 1,120 units, what are estimated total overhead costs in September [round unit costs to two decimal places] If September production is expected to be 1,120 units, what are estimated total overhead costs in September [round unit costs to two decimal places

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)
