500 represents the initial amount of medication, since when t=0, a=500.
Answer:
0.14
Step-by-step explanation:
The way to solve this problem is to add everything together. 20+60 is 80, and there are two 30 gram slices of bread (30 x 2 = 60) so you add the 80 from before to the two slices of bread, which is 80 + 60, and that equals 140 grams total. Since there are 1000 grams in 1 kilogram, you have to divide this by 1000, giving you 0.14 or 14/1000.
