Which best describes the relationship between number of days and number of vitamins taken?

• Discrete, because you take the 2 vitamins all at once.

• Continuous, because you take the 2 vitamins all at once.

• Discrete, because you always take the same amount of vitamins.

• Continuous, because you always take the same amount of vitamins.

I started with $100 in my piggy bank. Each month, I add $5 more to my piggy bank.

What explicit equation would describe the relationship between the number of months adding money (x) and the total money in the piggy bank (y).

• y = 100 + 5x

• y = 100 + 5(x - 1)

• y = 100(5)^x

• y = 100(5)^x-1
