ashley opened a savings account with $4000 and was paid simple interest at an annual rate of 9%. When ashley closed the account, she was paid $1440 in interest. How long was the account opened for, in years?

4 years

Step-by-step explanation:

I=prt

1440=4000(r)0.09

4000r * 0.09 = 1440

divide both sides by 4000 times 0.09

r = 4

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
