Using proportions, it is found that the amount of the novel she would have read is:
D. 14/15.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:
Hence option D is correct.

Answer:
a. The linear function is given by,
y = 60x + 30 [y is in $ and x is in hour and x ≥ 0.5]
= 60 [for x < 0.5]
b. The total cost of the repair job is, $ 675 .
Step-by-step explanation:
Let, the linear function describing garage charge( y in $) and no. of hours of repair job ( x in hour) be,
y = mx + c [for x ≥ 0.5] -----------(1)
where, m is the slope of the line and c is the y intercept.
Now ,
m =
= 60 ----------------(2)
Now, putting the value of m and the point (x,y) = (0.5, 60) in (1), we get,
$
⇒ c = 30 ----------------- (3)
Hence, the linear function is given by,
y = 60x + 30 [y is in $ and x is in hour and x ≥ 0.5] ------------(4)
= 60 [for x < 0.5]
Now, putting
x = 4 hr 15 min
= hour
= 4.25 hour in (4), we get,
[in $]
= $ 285
So, the total cost of the repair job,
= $ (285 + 390)
= $ 675
