Let the additional amount saved be x for the next 5 years

The cash flows for the 14 years are

Year	Cash Flow
1	5800
2	5800
3	5800
4	5800
5	5800
6	5800+x
7	5800+x
8	5800+x
9	5800+x
10	5800+x
11	-38000
12	-38000
13	-38000
14	-38000

Since all the savings are used for tuition fees, the sum of present value of all cash flows at time = 0 should be zero

PV = CFn*PV Factor , where PV Factor = 1/(1+r)ⁿ

Given, r = 12%

Year	Cash Flow	PV Factor	PV
1	5800	0.8929	5178.82
2	5800	0.7972	4623.76
3	5800	0.7118	4128.44
4	5800	0.6355	3685.9
5	5800	0.5674	3290.92
6	5800+x	0.5066	0.5066(5800+x)
7	5800+x	0.4523	0.4523(5800+x)
8	5800+x	0.4039	0.4039(5800+x)
9	5800+x	0.3606	0.3606(5800+x)
10	5800+x	0.3220	0.322(5800+x)
11	-38000	0.2875	-10925
12	-38000	0.2567	-9754.6
13	-38000	0.2292	-8709.6
14	-38000	0.2046	-7774.8

Hence, NPV = sum of PV = -16256.16 + 2.0454(5800+x)

=> -16256.16 + 2.0454(5800+x) = 0

=> 5800 + x = 7947.6679

=> x = 2147.67

Hence, an additional amount of $2147.67 should be saved for the next 5 months
