The master family financed a computer that cost $1200. if the interest rate is 19%.how much will the family owe for the computer after one month if no payments are made?

The answer is $1219

Interest = Total amount * interest rate * time          ( I=prt is the formula for calculating interest)

In this case,

Total amount = $1200

Interest rate= $ 0.19

Time span for which interest rate is being calculated= 1/12 (since the rate is yearly and we are calculating interest for a month)

Interest = 1200*0.19*1/12 = 19

So the total amount owned by family at the end of one month = original amount + interest =  $1200 + $19 = $1219

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
