Final answer:
Each builder will be paid £72.19 today.
Step-by-step explanation:
To find out how much each builder will be paid today, we need to calculate the total amount of hours worked by the six builders yesterday and divide it by the number of builders available today.
Yesterday, the six builders worked for 5.5 hours to build the wall.
So, the total hours worked by the six builders is 6 * 5.5 = 33 hours.
Today, only four builders are available. To calculate the amount each builder will be paid, we will multiply the total hours worked (33 hours) by the hourly rate (£8.75) and divide it by the number of builders (4).
Each builder will be paid (33 * 8.75) / 4 = £72.1875.
Rounded to two decimal places, each builder will be paid £72.19 today.
