Answer:
The explicit rule for the arithmetic sequence is given by:
......[1]
where,
is the first term
n is the number of terms and
d is the common difference for two consecutive terms.
As per the statement:
A recursive rule for an arithmetic sequence is:
The recursive formula for the arithmetic sequence is given by:
then;
On comparing we get;
d = -3
Substitute the given values in [1] we have;
⇒
Therefore, the explicit rule for this sequence is,

Answer:
The contribution margin it's determined by the total amount of Gross Profit divided by the total value of sales.
Profit = $405,000
Sales = 11,250×106 =$1,192,500
Therefore contribution margin ratio = ($405,000/$1,192,500) = 0.34
The Break Even point is given thus;
Fixed cost = 25 × 11250 =$281,250
Break-even point = Fixed costs ÷ contribution ratio
= $281,250/0.34 = $827,205.88
