Answer:

A=P+I A=800+6.4  A=806.4

Step-by-step explanation: The interest is $6.4 and the amount is $806.4. Convert 8 months into years.

8 months =812 years=0.6667 years

Find an interest by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this examplee P = $800, i = 1.2% and t = 0.6667 years, so

I=P⋅i⋅t I=800⋅0.012⋅0.6667  I=6.4

STEP 3: Find an amount by using the formula A=P+I.

Since P = $800 and I = $6.4 we have

A=P+I A=800+6.4 A=806.
