licia wants to have a Grade Point Average of a B or better for the first semester. On this scale, an A is worth 4 points, a B is 3 points, a C is 2 points, a D is 1 point, and an F is worth 0 points. She knows she has an A in Social Studies, a C in English, and an A in Algebra. What is the lowest grade she can make in Science and still have a B for the semester?
\n" ); document.write( ":
\n" ); document.write( "Let S = the required grade in Science
\n" ); document.write( "Given:
\n" ); document.write( "Social S: A = 4
\n" ); document.write( "English: C = 2
\n" ); document.write( "Algebra: A = 4
\n" ); document.write( ":
\n" ); document.write( "\"%284+%2B+2+%2B+4+%2B+S%29%2F4\" = 3
\n" ); document.write( "Multiply equation by 4 to get rid of the denominator
\n" ); document.write( "4 + 2 + 4 + S = 12
\n" ); document.write( "10 + S = 12
\n" ); document.write( "S = 12 - 10
\n" ); document.write( "S = 2; she needs at least a C in Science
\n" ); document.write( ":
