Answer:
$3.94
Step-by-step explanation:
You will need to use the compound interest formula for this.

P = initial balance
r = interest rate
n = number of times compounded annually
t = time
Your equation will look like this:
= 3.94
A+(-1.3)=-4.5
Add 1.3 to both sides of the equation
a=-3.2
Use
bodmas
multiply 6 and 3= 18
then add the answer with 23
18+23=455
the answer you get, subtract it from 7
455-7=448
the answer is 448
