Answer:

S = 20 + 0.5*x (S is the total bill, x is the number of text messages)

Step-by-step explanation:

The cell phone company have a fixed value you have to pay every month, independently of the number of text messages you send, and that is $20.

For each text message, you pay an additional %0.50.

So, if you send 'x' text messages in a month, you will pay the fixed $20 plus $0.5 for each text messages: you will pay 0.5 times x for the messages.

So, we can formulate the following equation:

Being "S" the total price you will pay:

S = 20 + 0.5*x

You have $60 and your sister has $120. You are saving $14 per week and your sister is saving $10 per week. How long will it be b
tigry1 [53]

Answer:

15 weeks

The amount of money is  270

Step-by-step explanation:

You: 60 +14x

Sister: 120+10x

Set them equal to each other

60+14x = 120+10x

Subtract 10x from each side

60+4x= 120

Subtract 60 from each side

4x= 60

Divide by 4

4x/4 = 60/4

x = 15

15 weeks

The amount of money is 120+10*15 = 120+150 = 270
