Help please :(((((( ill givve brainly
SVETLANKA909090 [29]

Answer:

2.86 hours = £26.57

Step-by-step explanation:

5 builders = 3.5 hours

<u>Express it in ratio form:</u>

5 : 3.5 (B1:H1)

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

<u><em>Since This is an inverse proportion, it will be written like:</em></u>

=> B1:H1 = H2:B2

Where H2 = x(no. of hours)

=> 5 : 3.5 = x : 2

<u><em>Product of means = Product of Extremes</em></u>

=> 5*2 = 3.5x

=> 10 = 3.5 x

Dividing both sides by 3.5

=> x = 2.86 hours

<u><em>Now, On Tuesday:</em></u>

1 hour = £9.3

<u><em>For 2.86 hours,</em></u>

2.86 hours = £9.3 × 2.86

2.86 hours = £26.57
