P bricklayers q bricks/hour
1 bricklayer \(\frac{q}{p}\) bricks/hour
4 bricklayers \(\frac{4q}{p}\) bricks/hour
4 bricklayers at a rate of \(\frac{4q}{p}\)brikcs/hour for 8 hours = 8* \(\frac{4q}{p}\) = \(\frac{32q}{p}\)

p bricklayers can lay a total of q bricks per hour
So single person rate will be = \(q/p\)
how many bricks could One bricklayers lay in 8 hours:
R T W
\(q/p\) 8 = \(8q/p\)
how many bricks could 4 bricklayers lay in 8 hours
\(8q/p\) * 4 = \(32q/p\)
