Answer:
Maximum sales increase = $162,895.93
Explanation:
FN = (A/S0)?S–(L/S0)?S–MS1(RR)
A- Assets tied directly to sales
L-spontaneous liabilities that are affected by sales
S0=the previous year's sales
S1=total projected sales for next year
S=the change in sales between S0 and S1
MS1=projected net income
RR=the retention ratio from net income
$0 = ($2,600,000/$4,000,000)×(S1-S0)–($300,000/$4,000,000)×(S1-S0)–S1×5%×45%
$0 = ($2,600,000/$4,000,000)×(S1-$4,000,000)–($300,000/$4,000,000)×(S1-4,000,000)–S1×2.25%
$0 = 0.65×S1-$2,600,000–0.075×S1+$300,000–S1×2.25%
$2,300,000 = S1×(0.65-0.075-0.025)
S1 = $4,162,895.93
Maximum sales increase = $162,895.93
