Answer:
$575
Explanation:
Given that,
Opening office supplies = $1,100
Closing office supplies = $475
Office supplies expense for the month = $1,200
Opening stock + Purchases - Closing stock = Consumption
$1,100 + Purchases - $475 = $1,200
$625 + Purchases = $1,200
Purchases = $1,200 - $625
= $575
Therefore, the amount of office supplies was purchased during February is $575.

Answer:
the breakeven cash inflow for the project is $131474
Explanation:
given data
cost of capital = 10 percent
initial investment = $1,000,000
useful life = 15 year
to find out
the breakeven cash inflow for the project
solution
first we consider here annual cash inflows that is = x
now break even point is the one at which the net present value of the project = 0
so we can say that here
Present value of cash inflows - Present value of cash outflows = 0 .................1
here we know Present value of cash inflows = x × PVAF ( 10%,15 years)
Present value of cash inflows = x × 7.6060
put value in equation 1 we get
x × 7.6060 - $1,000,000 = 0
solve and we get x
x = 
x = $131474
so the breakeven cash inflow for the project is $131474
