Can someone show the correct way to work the following problem? |
Lori and Jon work in the toy department of the J-Mart discount store. Lori can assemble a bike in x minutes and Jon can assemble a bike in x-16 minutes. Write an algebraic expression for the number of bikes they can assemble if they work together for a ten hour shift. di ko alam eh... Lori can assemble 1/x bikes in a minute =60/x bikes in an hour =600/x bikes in 10 hours. Jon can assemble 1/(x-16) bikes in a minute =60/(x-16) bikes in an hour =600/(x-16) bikes in 10 hours. number of bikes they can assemble if they work together for a ten hour shift =600/x+600/(x-16) =[600(x-16)+600x]/[x(x-16)] =[1200(x-8)]/[x(x-16)] N(1/x + 1/(x - 16)) = 10*60 x +(x-16) = 600 |
