Lili24 Phil has 11 stamps of denominations $0.37 and$0.23. If the total value of the stamps is $3.23 how many$0.37 stamps does Phil have? one year ago one year ago

1. sheg

let phil has x number of stamps of \$0.37 denomination then he will be having (11-x) number of stamps of @0.23 denomination in this case ${{0.37}\times{x}}+{{0.23}\times(11-x)} = 3.23$ now solve this equation

Is it -0.0371??

3. sheg

no

4. sheg

${0.37x}-{0.23x}= 3.23 - 0.23\times11$ $0.14x = 3.23 - 2.53$ $0.14x = 0.7$ $x= {{0.7}\over{0.14}}=5$
