Answer:
$2,259.71
Step-by-step explanation:
(refer to attached)
the formula for compound interest is:
A = P [ 1 + (r/n) ] ^ (nt)
Where,
A = final amount
P = principal amount (given as $600)
r = interest rate = 7% = 0.07
n = 12 (because compounded monthly)
t = time elapsed (given as 19 years)
Substituting these into our equation,
A = P [ 1 + (r/n) ] ^ (nt)
A = 600 [ 1 + (0.07/12) ] ^ [(12)(19)]
A = 600 [ 1 + 0.005833 ] ^ 228
A = 600 [ 1.005833 ] ^ 228
A = 600 [ 3.7662 ]
A = $2,259.71
Answer:mr.Sinofsky used 2 tanks of gas altogether
Step-by-step explanation:
Mr.Sinofsky used 5/8 of a tank of gas on a trip to visit relatives for the weekend.
He used another 1 half of a tank commuting to work the next week. Converting 1 1/2 tank of gas to improper fraction, it becomes 3/2 tanks of gas.
He then took another weekend trip and use 1/4 tank of gas. Therefore, the total number of tanks of gas that Mr.Sinofsky used would be
5/8 + 3/2 + 1/4 = (5 + 12 + 2)/8 = 19/8
= 2 tanks of gas
