When katie was born her mother invested $5000 in an account for her college savings. we can use the formula v = 5000(1 + r)t where r represents the interest rate and t represents the time in years. if katie has approximately $11,042 in her account after 18 years, what was the interest rate for the account?

The solution is 4.5%. To calculate the amount for 4.5 percent, plug .045 in the formula V = 5000(1 + r)18. The result is approximately $11,042.

Step-by-step explanation:

6 equilateral triangles

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
