move all terms that dont contain y to the right side and solve
I do not know if this is completely correct
<u>25 hours</u>
It takes 5 men 45 hours to build a wall.
So, if no. of men increases by 1.8 [∴ 5 x 1.8 = 9],
then time taken reduces by that same amount.
=> 45 hours / 1.8
=> 45 / (9/5)
=> 45 x 5 / 9
=> 5 x 5
=> <u>25 hours</u>
y = total cost
x = # of hours
$12 + $8x = y
Answer$18.12
24.99+5.25-12.12=$18.12
