Match the information about interest earned with the principal amount invested. Remember the equation for calculating simple interest is i=prt. $45 over 3 years at an interest rate of 3% $48 over 4 years at an interest rate of 3% $42 over 3 years at an interest rate of 2% $30 over 1 year at an interest rate of 5%

in the equation: i is the interest earned p is the principal amount r is the interest rate t is the number of years

ok i did this but when i get the answer its like 4 or 5 dollars when the answers are p=$500 P=$600 and stuff like that @user2486

OpenStudy (anonymous):

p=$500 p=$600 p=$400 p=$700

I think you may have plugged the small dollar amount given into the wrong part. The way I understand it the $45 would be the i. So 45=p*.03*3 and then when you solve for p you get: \[\frac{ 45 }{ 3*.03 }\]
