Donald has $30in a savings account that earns
5 %
annually..howmuchwillhehavein1year?

use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

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

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;

Principle amount=$30

Interest amount=Principle amount×interest×number of years

interest=5%=5/100=0.05

number of years=1

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

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
