gladu [14]

Answer:

To calculate compounded interest, use the compound interest formula.

A(t)=P(1+rn)n⋅t

Recognize the information given in the problem.

P=2560,r=0.035,n=1,t=4

Substitute the values into the appropriate position in the formula.

A(4)=2560(1+0.0351)1⋅4

Simplify by multiplying and dividing by 1.

A(4)=2560(1+0.035)4

Simplify using the order of operations.

A(4)=$2,937.66

The balance at the end of 4 years would be $2,937.66.
