Answer:
Step-by-step explanation:
Let x represent the number of miles after which the cost of both options will be the same.
You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is
0.8x + 30
Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is
2.3x
An equation to show after how many rides the cost will be the same would be
0.8x + 30 = 2.3x
2.3x - 0.8x = 30
1.5x = 30
If x = 16 and y = -16, then x+y = 16+(-16) = 0
Alternatively, if x = -16 and y = 16, then x+y = -16+16 = 0
So y = -x and x can be equal to either 16 or -16
Answer:
20 years old
Step-by-step explanation:
Let us assume that the son's age is x.
Therefore,
2.5x = 55 - 5
2.5x = 50
x = 20 years old
