A total of 90 bricks were laid that day.
Step-by-step explanation:
Given,
Number of bricks laid in one hour = 27
This represents 30% of total bricks laid that day.
Let,
x be the total number of bricks laid that day.
30% of x = 27
[tex]\frac{30}{100}*x=27\\0.3x=27[/tex]
Dividing both sides by 0.3
[tex]\frac{0.3x}{0.3}=\frac{27}{0.3}\\x=90[/tex]
A total of 90 bricks were laid that day.
