The formula is
A=pe^(r×t/12)
A future value 543
P present value 500
R interest rate 0.065
E constant
T time t ( in months)
Solve the formula for t
T/12=[log (A/p)÷log (e)]÷r
T/12=(log(543÷500)÷log(e))÷0.065
T/12=1.3
T=1.3×12
T=15 months
25% is 0.25 in decimal form
800+25% of 800
800+(0.25×800)
800+200
1000 is the price
