Answer:
42x+−17
Step-by-step explanation:
(7)(6x)+(7)(−4)+11
42x+ −28 + 11
(42x)+(−28+11)
42x+−17
The formula for compound interest is the following:
A=P(1+r/n)^nt
A=accumulated amount (what we're looking for)
P=Principal amount (initial amount). $800 in this case
r=rate. 0.09 in this case which we get from converting 9% to decimal by dividing by a 100.
n=number of times interest is compounded. In this case semi-annually which means 2
t=time. In this case 4 years
Let's calculate:
A=800(1+0.09/2)^(2*4)
A=800(1+0.045)^8
A=800(1.045)^8
A=800(1.42210061284)
A=1137.68049027
Let's round to the hundredth place (to represent cents) since the amount represents money.
Answer=The balance after 4 years will be $1,137.68
3/4 i believe, you simply divide both numbers by 84 to get your answer
