Answer:
[tex]\text{Total}=89,284[/tex]Step-by-step explanation:
Simple interest is represented as:
[tex]\begin{gathered} I=Prt \\ where, \\ I=\text{ interest } \\ P=\text{ principal} \\ r=\text{ interest rate } \\ t=\text{ time (years)} \end{gathered}[/tex]Then, the interest for a living room suite of 85,000 at a 12% simple interest.
[tex]\begin{gathered} I=85000\cdot0.12\cdot\text{0}.42 \\ I=4,284 \end{gathered}[/tex]Hence, he will pay for the furniture at the original price plus interest:
[tex]\begin{gathered} \text{Total}=\text{ 85,000+4,284} \\ \text{Total}=89,284 \end{gathered}[/tex]
