Question 1154320
how do you find the interest rate of this account math word problem? Serena places $2000 in an interest-earning account where the interest compounds annually,after twoyears there is $2130.60in the account> use this formula $2000(1+r)^2=2123.60
<pre>{{{matrix(1,3, "2,000"(1 + r)^2, "=", "2,123.60")}}}
       {{{matrix(1,3, (1 + r)^2, "=", "2,123.6"/"2,000")}}}
       {{{matrix(1,3, 1 + r, "=", sqrt("2,123.6"/"2,000"))}}}
       Interest rate, or {{{highlight_green(matrix(1,7, r, "=", sqrt("2,123.6"/"2,000") - 1, "=", "0.030436801,", or, "3.044%"))}}}
