help please :(((((( ill givve brainly

Answer 1

Answer:

2.86 hours = £26.57

Step-by-step explanation:

5 builders = 3.5 hours

Express it in ratio form:

5 : 3.5 (B1:H1)

However, on Tuesday 2 builders(B2) are available. We can set up a proportion to find the number of hours.

Since This is an inverse proportion, it will be written like:

=> B1:H1 = H2:B2

Where H2 = x(no. of hours)

=> 5 : 3.5 = x : 2

Product of means = Product of Extremes

=> 5*2 = 3.5x

=> 10 = 3.5 x

Dividing both sides by 3.5

=> x = 2.86 hours

Now, On Tuesday:

1 hour = £9.3

For 2.86 hours,

2.86 hours = £9.3 × 2.86

2.86 hours = £26.57

Answer 2

Answer:

£83.7

Step-by-step explanation:

Since the amount of work is same:

Total time required: 5*3.5= 17.5 hours

Time split between 2 builders= 17.5/2= 8.75 hours ≈ 9 hours

It is counted as full hours as the builders get paid same for incomplete hours.

Each builder gets= 9*£9.30= £83.7
