$ 142.5

Explanation

to solve this we can use the formula:

[tex]i=\text{Prt}[/tex]

where i is the interest, P is the principal, r is the rate ( in decimals) and t is the time

then

Step 1

Let

[tex]\begin{gathered} i=i \\ P=950 \\ r=3\text{ \% =0.03} \\ \text{Time= 5 years} \end{gathered}[/tex]

replace in the formula

[tex]\begin{gathered} i=950\cdot0.03\cdot5 \\ i=142.5 \end{gathered}[/tex]

hence, the answer is

$ 142.5

I hope this helps you
