Simple interest means the interest at the end of each year will always be 8% of 2000 (assuming he doesnt pay some of it off), and will not be compounded with the existing interest.
To get a percentage, multiply by the percentage/100, in this case i.e. multiply by 0.08.
2000*0.08 = $160.
Therefore he has $160 of interest each year to pay.
Now we just need to work out how many lots of 160 go into 640, i.e. divide through.
640/160 = 4 - therefore he has had the loan for 4 years.
Answer:
y=3x-2
For plotting graph we have to put some x values in above equation then we get y Ans
when x=0,y=-2
when x=1,y=1
when x=2,y=4
when x=-1, y=-5
when x=-2, y=-8
Step-by-step explanation:
Find what 64% of 325 is, it's 208. (to find this do 325 x .64)
Now do 325-208, 117.
