Answer:
$360
Explanation:
Given
Amount borrowed P = $4500 (principal)
Time T = 2 years
Rate R = 4
Simple interest formula is expressed as;
SI = PRT/100
Substitute the given parameters into the formula
SI = 4500×2×4/100
SI = 45×2×4
SI = 45×8
SI = $360
The amount of interest he will have to pay is $360
