Answer:
-6
Step-by-step explanation:
Let the number be 'x'
Sum of a number and one = x + 1
Sum of a number and one is doubled = 2*(x +1) = 2*x + 2*1 = 2x + 2
Four less than the number = x - 4
2x + 2 = x - 4
Subtract 'x' from both sides
2x - x + 2 = x - x - 4
x + 2 = -4
No, subtract 2 form both sides
x + 2 -2 = - 4 - 2
x = -6
Let's assume m represent the mileage of the car.
Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.
So, the total charge for this agency = 33 + 0.20m.
Similarly total charge of the ultimo car = 17 + 0.85m.
Now we need to find the daily mileage for which the ultimo charge is four times the primo charge . So, we can set up an equation as following:
17 + 0.85m = 4 *( 33 + 0.20m )
17 + 0.85m = 132 + 0.80m By distribution property.
17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.
17 + 0.05m = 132
17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.
0.05m = 115
Divide each by 0.05.
So, m = 2300
Hence, the daily mileage is 2300 miles.
