Answer:
A(t) = 5000(1 +.05/4)^(4t)
Step-by-step explanation:
The compound interest formula is ...
A = P(1 +r/n)^(nt)
where principal P earns interest at annual rate r compounded n times per year for t years. The problem statement tells you P=5000, r=0.05, n=4. Putting these values into the formula gives ...
A(t) = 5000(1 +0.05/4)^(4t)
Divide $31.75 by 2 to find out the cost for 1 pack. Then multiply that total times 3 to get the total for 3 packs.
31.75/2 = 15.875
15.875 x 3 = 47.625, rounded to $47.63
The only option that fits is E, because:
f(10)=4×10+10=50
