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
The answers are A., C., and E.
The chart shows that Camila has a greater rate of change than Lydia, so B is incorrect. C and E are true because the graph shows that Camila's rate of change is $7/hour, making C true, which means that in 2 hours, she gets paid $14, making E true.
Answers: A., C., and E.
