Answer:
x = 5
z =2
y =4.4
Step-by-step explanation:
y varies directly as x
y = kx
and inversely as z
y = kx/z
Putting in the numbers in the first line of the table, we can solve for k
13.75 = k * 25/4
Multiply by 4
13.75*4 = 25k
55 =25k
Divide by 25
55/25 = 25k/25
2.2 = k
Now we can fill in the table
y = 2.2 x/z
Row 2 we need to find x
1 = 2.2 x/11
Multiply by 11
11 = 2.2 x
Divide by 2.2
11/2.2 = 2.2x
5 =x
Row 3 we need to find z
18.7 = 2.2 *17/z
18.7 = 37.4 /z
Multiply by z
18.7z = 37.4
Divide by 18.7
18.7/18.7z = 37.4/18.8
z =2
Row 4 we need to find y
y = 2.2 *10/5
y = 22/5
y =4.4

Answer:
c. $3,174
Step-by-step explanation:
Using a financial calculator, enter the following inputs to find the Present value (PV) ;
Future value; FV = 4,200
Total duration ; N = 2,920 <em>(365 days in a year times 8 years; 8 * 365 = 2920)</em>
Daily interest rate; I = 3.5% /365 = 0.009589%
PMT = 0
then CPT PV = 3,174.338
Therefore, Arya should deposit $3,174
