Answer: In order to save money for a 1 day rental with plan B, the number of miles must be greater than 153.84 miles
Step-by-step explanation:
Let x represent the number of miles driven with either plan A or B.
Plan A: 30 dollars per day and 13 cents per mile. It means that the cost of renting the car or one day and driving x miles is
30 + 0.13x
Plan B: 50 dollars per day with free unlimited mileage. It means that the cost of renting the car or one day and driving x miles is 50
In order to save money for a 1 day rental with plan B, the number of miles would be
50 < 30 + 0.13x
50 - 30 < 0.13x
20 < 0.13x
0.13x > 20
x > 20/0.13
x > 153.84 miles
5=ones
2=tens
5=hundreds
4=thousands
3=ten thousands
Answer:
x=3 y=4
Step-by-step explanation:
x+y=7; x + 2y =11
step: solve x + y = 7 for x:
x + y+ -y =7 + -y (add -y to both sides)
x = -y + 7
step: substitute -y + 7 for x in x + 2y =11:
x + 2y = 11
-y + 7 + 2y = 11
y + 7 =11(simplify both sides of the equation)
y + 7 + -7 = 11 + -7 (add -7 to both sides)
y = 4
step: substitute 4 for y in x = -y + 7:
x = -y +7
x = -4 + 7
x = 3 (simplify both sides of the equation)
