A solid yellow stripe is to be painted in the middle of a certain highway. If 1 gallon of paint covers an area of w square feet of highway, how many gallons of paint will be needed to paint a stripe of t inches wide on a stretch of highway m miles long? (1 mile = 5,280 feet and 1 foot = 12 inches) Choose the correct choice from the following:
A) (5,280 mt) / 12 w
B) (5,280 pt) / 12m
C) (5,280 pmt) /12
D) (5,280)(12m) / pt
E) (5,280)(12p) / mt
Given that: 1 gallon of paint covers an area ofwsquare feet. Question:how many gallonsof paint will be needed ...   In any case you will have:(total area in square feet)/(gallons per feet)=(total area in square feet)/w, so w must be in the denominator: eliminate all but A and D.   Now, lets see where should be t: (area in square feet)=(width in feet)*(length in feet) --&gt; width=tinchesas1 feet=12 inchesthent inches=t/12 feet, so (area in square feet)=(t/12) * (length in feet), so t must be in the nominator: only A is left.   (5,280 mt) / 12 wnswer: (5,280 mt) / 12 w.
