Algebra.Com's Answer #648023 by sheffydavid@gmail.com(2)![]() ![]() ![]() You can put this solution on YOUR website! Let the number of toppings be x. \n" ); document.write( "Cost of Antonio's pizza = $8 + $1.5x\r \n" ); document.write( "\n" ); document.write( "And cost of Zina's pizza = $10 + $1x\r \n" ); document.write( "\n" ); document.write( "Now, given that the cost of the two pizza's is the same.\r \n" ); document.write( "\n" ); document.write( "=> $8 + $1.5x = $10 + $1x\r \n" ); document.write( "\n" ); document.write( "=> 1.5x - x = 10 - 8\r \n" ); document.write( "\n" ); document.write( "=> 0.5x = 2\r \n" ); document.write( "\n" ); document.write( "=> x = 4\r \n" ); document.write( "\n" ); document.write( "Therefore, the number of toppings is 4.\r \n" ); document.write( "\n" ); document.write( "Since both the pizzas cost the same when the number of toppings is 4, we can find the cost of any one of the two pizzas.\r \n" ); document.write( "\n" ); document.write( "Cost of a pizza will be \n" ); document.write( "$10 + ($1 x 4) \n" ); document.write( "= $10 + $4 \n" ); document.write( "= $14 \n" ); document.write( " \n" ); document.write( " |
