Answer:
the answer is 40
Step-by-step explanation:
because when you estimate 1 it will give you zero for example from 1234=0 56789 =1 so 1=to zero so the answer is 40
#1: 4*5 + 4*6=20+24=44
#2: 4*(5+6)=4*11=44
we know that
The formula of simple interest is equal to

In this problem
we have
I=$170
P=$8,500
r=4%=4/100=0.04
t=?
substitute given values in the formula

therefore
0.5 years=6 months
<h2>The answer is 6 months</h2>
The LCM of 120 and 150 is 600
