document.write( "A landscaping company mixes its own proprietary blend of topsoil that costs $29.55 per ton to make. The blend contains soil that costs $25.05 per ton and organic compost that costs $36.30 per ton. If the company already has 3 tons of soil on hand, how many tons of compost do they need to mix in?\r

Algebra.Com's Answer #645754 by josgarithmetic(39625) ![]() You can put this solution on YOUR website! This should or can be split into two separate problems. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Here is the first problem: \n" ); document.write( "own proprietary blend of topsoil that costs $29.55 per ton to make. The blend contains soil that costs $25.05 per ton and organic compost that costs $36.30 per ton. \n" ); document.write( "Solve for the proportions of the two materials making the topsoil.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then the second problem: \n" ); document.write( "the company already has 3 tons of soil on hand, how many tons of compost do they need to mix in? \n" ); document.write( "This is turned into simply a proportion problem, or the equality of two ratios.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You might try handling the first problem using just a single variable, say x for the tons of the $25.05 soil; and 100-x for the tons of the $36.30 per ton organic compost; and this would be for 100 tons of the proprietary blend. The pricing is per TON. Look at COST per TON. \n" ); document.write( "- \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve for x and compute 100-x. \n" ); document.write( "Then go to problems number 2. \n" ); document.write( " |
