Answer:
1.25$/per quart of oil. 14.05 starting fee.
Step-by-step explanation:
Give a variable that one quart of oil is o.
5o + starting fee +2.5 = 7o + starting fee
2o = 2.5
o = 1.25
substitute and we know starting fee is 14.05
The answer is x bc when you decreasing the interval f(x) it will equal (-2)
6.) 15.7 because you would multiple 3.14 by the diameter of 5. Then divide by .5.<span />
