A store owner borrowed $\$ 39,000$ at $10 \%$ from a bank to buy more inventory. Given that the loan is for 21 months, find the interest and the maturity value.
The interest is $\$ \square$.
The maturity value is $\$ \square$.
\(\boxed{M = $45,825}\)
Step 1 :\(I = P*r*t\)
Step 2 :\(I = $39,000 * 0.10 * 1.75\)
Step 3 :\(I = $6,825\)
Step 4 :\(M = P + I\)
Step 5 :\(M = $39,000 + $6,825\)
Step 6 :\(\boxed{M = $45,825}\)
