Solve the problem.Simple interest is calculated using the formula, interest = principal ? rate ? time or i = prt. Jenny Brooks invested a certain amount of money saved for 1 year at a certain annual interest rate (simple interest) yielded $6.75 in interest. If we had added $90 to the principal and reduced the interest rate by 2 percentage point(s), the interest would have been the same. Find the principal and the rate.
A. $135.00, 5% B. $7.00, 5% C. $7.00, 3% D. $9.06, 630%
