Answer:
about 4.63 teaspoons
Step-by-step explanation:
You can write the proportion ...
(teaspoons)/(fraction of RDA) = 1.75/0.85 = x/2.25
where x represents the unknown number of teaspoons. Multiplying by 2.25 gives you ...
x = 2.25(1.75/0.85) = 4.632...
About 4.63 teaspoons of vitamin will supply 2.25 times the RDA.

QUESTION:
A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent full. how fast did the battery charge and how long did it take?
Solution :
<u>Given</u>
- Initial amount of charge = 23%
- Amount after charge = 89%
<u>procedu</u><u>re</u>
Let the rate of charging be r .
r = (change in charge level) / (time interval) = (89% - 23%) / (30 min) = 2.2 % per minute
charge = (rate of charging)(time) + (initial charge)
100% = r*t + 23%
100% = (2.2 %/min)t + 23%
Solve for t and get
t = [(100 - 23) / 2.2]
Answer = 35 min
