Donald has $30in a savings account that earns

Step-by-step explanation:

The total amount he will earn in a year can be expressed as;

The total amount=Principle amount+interest amount

where;

Interest amount=Principle amount×interest×number of years

Interest amount=(30×0.05×1)=1.5

replacing;

Total amount=(30+1.5)=31.5

The total amount he will have in a year=$31.5
