Answer:
[50, 410]
Step-by-step explanation:
If the plumber works 0 hours, he still charges $50, so that is the minimum of the range of charges.
If the plumber works 8 hours, his hourly charge of 8×$45 = $360 is added to his fixed charge of $50 for a total of $410. That is the maximum of the range of daily charges.
The range of the function is $50 to $410.
$55.25c ☺️ Because 10% of 65 is $6.50 and 5% of $3.25 and 6.50 + 3.25 = 9.75 and 65 - 9.75 = 55.25 ☺️ Hope I helped ☺️
Find the change between the first two sets:
12-9 = 3
14.4 - 10.8 = 3.6
3.6/3 = 1.2
Now find the change between the last two sets:
12 - -3 = 15
14.4 - 3.6 = 10.8
10.8/15 = 0.72
1.2 does not equal 0.72 so the answer is No
