Bridgett has 64 coins in nickels and dimes. What is the minimum number of dimes she should have to at least $4.55? Set up the inequality and solve.

\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq: n + d = 64
\n" ); document.write( "Value Eq::: 5n+10d >= 455 cents
\n" ); document.write( "----------------------------------
\n" ); document.write( "Multiply thru the 1st Eq. by 5 to get:
\n" ); document.write( "5n + 5d = 5*64
\n" ); document.write( "5n + 10d >= 455
\n" ); document.write( "--------------------
\n" ); document.write( "5d >= 135
\n" ); document.write( "d >= 27 (# of dimes)
\n" ); document.write( "---
\n" ); document.write( "n <= 64-d = 64-27 = 34 (# of nickels
