Answer this plz, i really need it

A - 600

B - 3,100

Step-by-step explanation:

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 1.2%/100 = 0.012 per year.

Solving our equation:

A = 2500(1 + (0.012 × 20)) = 3100

A = $3,100.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,500.00 at a rate of 1.2% per year for 20 years is $3,100.00.

a.)the line for function b is steeper
