Originally,
Let x = the balance in the first account.
Let y = the balance in the second account.

The total amount in the two accounts is $9,000, therefore
x + y = 9000                      (1)

Zack withdraws 10% of x and 60% of y for a total of $2,175.
Therefore
0.1x + 0.6y = 2175
or
x + 6y = 21750                   (2)

Subtract (1) from (2).
x + 6y - (x + y) = 21750 - 9000
5y = 12750
y = 2550
From (1), obtain
x = 9000 - 2550 = 6450

The balance in the first account is
0.9*x = 0.9*6450 = $5,805
The remaining balance in the second account is
0.4*y = 0.4*2550 = $1,020

Answer:
The balance in the first account is $5,805
The balance in the second account is $1,020

What is one explanation for why this labor supply curve is upward sloping? the opportunity cost of leisure decreases as wages de
san4es73 [151]
I believe the correct answer is the first option. The labor supply curve is upward sloping because the opportunity cost of leisure decreases as wages decrease and the opposite of such is true as well. As one work one hour more, one will have less time for other activities. As the work rate increases in value, then the opportunity cost increases as well.
