Answer:
At the end of 4 years, Mr Davis will have $1462.50 in his account
Explanation:
Simple Interest SI = (Principal P × Rate R × Time T)/100
SI = (P × R × T)/100
P = $1250, R = 4.25%, T = 4 years
SI = ($1250 × 4.25 × 4)/100
SI = (21250)/100
SI = $212.50
The balance will therefore be
$1250 + $212.50 = $1462.50
