darnells's car used 8 gallons of gasoline to travel 340 miles.After a mechanic worked on the car it used 7 gallons of gasoline t
o travel 350 miles. If the price of the gasoline was approximately $4.00 a gallon,to the nearest cent per mile,did it cost to run the car after the mechanic worked on it
If it is $4.00 per gallon then we need to find the price of 7 gallons. 7 * 4.00 = 28 so it costs $28 to travel 350 miles. no to find the cost per mile, we need to divide. 350 / 28 = 12.5 so the cost to run the car per mile is $12.50
75+5m=50+7.5m -50 from both sides 25+5m=7.5m -5m from both sides 25=2.5m divide both sides by 2.5 10=m for 10therefor 75+5m<50+7.5m he must sell 11 memberships.
