Solve the following quadratic application using the Square Root Property.Find at what rate of interest Pat will need to invest $3700 for 2 years to get a return of $5190. (Use 
where P is the original amount deposited in the account, A is the amount in the account at the end of 2 years, and r is the rate of return.) Approximate r to the nearest hundredth when necessary; then convert it to a percentage.
A. The rate of interest will need to be approximately -0.02 = -2%. B. The rate of interest will need to be approximately 1.08 = 108%. C. The rate of interest will need to be approximately 0.18 = 18%. D. The rate of interest will need to be approximately 2.48 = 248%.
