Step-by-step explanation:
Answer:it will take 5 years
Step-by-step explanation:
Initial amount deposited into the account is $500 This means that the principal is
P = 500
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 1
The rate at which the principal was compounded is 5.6%. So
r = 5.6/100 = 0.056
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. A is already given as $750
Therefore,
750 = 500 (1+0.056/4)^4×t
750 = 500 (1+0.014)^4t
750 = 500 (1.014)^4t
(1.014)^4t = 750/500 = 1.5
Take root 1/4 of both sides
(1.014)^4t ×1/4 = 1.5^1/4
(1.014)^t = 1.107
t = 5 years
Answer:
a)The quantity (mg) of medication used to the nearest hundredths is 212.75mg
b) The quantity (mg) of the original medication left in the stock bottle to the nearest tenths is 287.3 mg.
Step-by-step explanation:
For question a) 125mg + 62.5mg +25.25mg= 212.75 mg to the nearest hundredths
b) The quantity left can be calculated by subtracting 212.75 from 500
500 - 212.75 = 287.25 to the nearest tenth is 287.3mg
It’s C because I got an A on that quiz and it was pretty hard
