Answer:
38.3 hours
Step-by-step explanation:
Given data
We have been given the function that describes his pay, which is
y=6.50h
Where h is the number of hours
now we have the amount y= 249
substitute
249=6.50*h
make the subject of the formula
249/6.5=h
h=38.3
Hence he needs to work for at least 38.3 hours
A
k < - 1
28 + 3k < 5(-3-8k)
28 + 3k < - 15 - 40k
28 + 15 < - 40k - 3k
43 < - 43k
43/- 43 > k (switch signs because 43 is negative)
k < -1
