document.write( "Question 288300: Homespun Jellies charges $2.49 for each jar of preserves. Shipping charges are $3.75 for handling, plus $0.60 per jar. Find a linear function for determining the cost of buying and shipping x jars of preserves. \n" ); document.write( "
Algebra.Com's Answer #208980 by jaydducote(11)![]() ![]() You can put this solution on YOUR website! Let \"x\" represent the number of unsold jars. \n" ); document.write( "2.49 per jar will be 2.49x \n" ); document.write( "3.75 for shipping and handling is constant, so no variable \n" ); document.write( "plus 0.60 for each jar, or 0.60x \n" ); document.write( "we'll let \"y\" equal the total cost\r \n" ); document.write( "\n" ); document.write( "y=2.49x+3.75+0.60x\r \n" ); document.write( "\n" ); document.write( "combine like terms to get: \n" ); document.write( "y=3.09x+3.75\r \n" ); document.write( "\n" ); document.write( "That is your linear function. For any number of jars sold, plug it into x and y will be the total cost. \n" ); document.write( " |
