"Simple interest" means the interest goes into a separate bucket, and
it just waits there for you to come and get it. It <em><u>doesn't</u></em> get added to the
amount in the account, so next year, you don't get interest on the interest.
4 percent of $2000 is (0.04 x 2000) = $80 .
That's how much interest you get each year.
At the end of 4 years, you have (4 x $80) = <u>$320</u> in the interest bucket.
(And of course, you still have the original $2000 in the account.)
The answer as a decimal is -42.6
So remember that the distance formula is 
.
1.
Distance between (4,-5) and (4,-2) is 3 units.
2.
Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
69. Oh yes the memes indeed.
Let Cynthia's age be C, then Abigail's age A
since Abigail is 8 years older, her age A = C+8.
20 years ago Cynthia's she was C-20 and Abigail was A-20=3(C-20)
A-20=3C-60
A=3C-40
but we just said A=C+8
so 3C-40=C+8
2C=48
C=24
A=24+8=32
Cynthia's age is 24 and Abigail's age is 32
