If you pay your bill in full you might avoid paying interest, depending on the rules behind the card. Keep in mind that the actual interest rate for your first card will be MUCH higher than that, so if the card was 20% APR and you spent that same $100 your interest for the month would be more like $1.67.Interest on $1000 would be $16+ a month.f you pay your bill in full you might avoid paying interest, depending on the rules behind the card.

1 In a hypertonic solution, the extracellular fluid has a higher osmolarity than the fluid inside the cell; water leaves the cell.  In an isotonic solution, the extracellular fluid has the same osmolarity as the cell; there will be no net movement of water into or out of the cell.
Cells in an isotonic solution retain their shape. Cells in a hypotonic solution swell as water enters the cell, and may burst if the concentration gradient is large enough between the inside and outside of the cell. Cells in a hypertonic solution shrink as water exits the cell, becoming shriveled.
