Answer: See explanation
Explanation:
Based on the information given in the question, the amount of borrowing that's required will be:
= [ rr * ( D - O)] - (R-O)
where,
rr = reserve requirement = 10% = 0.1
D = checkable deposits = $80
R = reserves = $15
O = deposits outflow = $6
= [ 0.10 × ($80 - $6)] - ($15 - $6)
= [ 0.10 × $74 ] - $9
= $7.4 - $9
= -$1.60
