Answer: £ 81.38
Step-by-step explanation:
Given: On Monday,
5 builders took hours ( i.e. hours ) to build a wall.
On Tuesday, only 2 builders were available.
As workers are inversely proportional to the time if the job remains constant.
Inverse variation equation :
Let x be the time taken by 2 builders, then
So, 2 builders will take 8.75 hours.
Each paid £9.30 for each hour.
Then, each builder will be paid for the work completed on Tuesday = £9.30 x 8.75
≈ £ 81.38
Hence, each builder will be paid £ 81.38 for the work completed on Tuesday .
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Question 1: Please see the answer at the photo, remember that when number of quartz is = 1 , Price per quartz = 2. This will be merge against each other.
This step will be repeated for the remaining figure.
Question 2:
As an be seen from the scatter plot, price per quart decrease when the number of quarts increase so the relation between the two variable show a negative association
Hope it will find you well.
