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
