Answer:
$46.8
Step-by-step explanation:
The shoe is worth $85. You pay a deposit of $40. The balance is $45.
So $45 is charged at 8% interest for six months.
Simple interest I= p x r x t
In this case, p is $45,
r is 8%
t= 6 months or 0.5 years
I = $45 x 8/100 x 0.5
I= $45 x 0.08 x 0.5
I=$1.8
The total amount owed will be $45 + $1.8
=$46.8
