document.write( "1.) A group of people would like to buy a vacation cabin for $600,000 sharing the cost equally. If they could find 5 more people to join them, each person's share would be reduced by $6000. How many people are in the group?\r

document.write( "3.) A person standing on the roof of a building and throw a ball directly upward. The ball misses the rooftop on its way down and eventually strikes the ground. The function S(t)=-16t2+64t+80 descrobes the ball's height above the ground, S(t) in feet. T seconds after it was thrown \n" );

Algebra.Com's Answer #345139 by godeapurva(7)![]() ![]() You can put this solution on YOUR website! Answer for your question no 1 \n" ); document.write( "Cost of the cabin is 600000$ \n" ); document.write( "Let the no of people be X , now they have mentioned that if 5 more people join the sharing each will save 6000$ \n" ); document.write( "So the amount contributed by each of X members is obviously > 6000$ \n" ); document.write( "And for that the number of contributors should also be less. \n" ); document.write( "Now take 2 values 20 & 25 \n" ); document.write( "if x is 20 then contribution is 600000/20 = 30,000 \n" ); document.write( "and x+5 that is 25, then 600000/25 = 24,000 \n" ); document.write( "thus 30000-24000= 6000$ \n" ); document.write( "This fits our requirement. \n" ); document.write( "Ans 25 people\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Another method is \n" ); document.write( "Let no of contributors = x \n" ); document.write( "and contribution made = y \n" ); document.write( "thus x*y = 600000 \n" ); document.write( "now (x+5)(y-6000)=600000 \n" ); document.write( "Now solve to get values for x and y \n" ); document.write( "This will take much longer time than the 1st one. \n" ); document.write( " |
