The number of coins jada will have on the eighth day, if jada starts with one coin and the number of coins doubles every day. (she has two coins on the first day of the doubling.

256 Coins

Step-by-step explanation:

On the first day, Jada starts with one coin, so all you have to do here is multiply it by 2.

Day 1: 2 coins

Day 2: 2 x 2 = 4 coins

Day 3: 4 x 2 = 8 coins

Day 4: 8 x 2 = 16 coins

Day 5: 16 x 2 = 32 coins

Day 6: 32 x 2 = 64 coins

Day 7: 64 x 2 = 128 coins

Day 8: 128 x 2 = 256 coins
