Answer:
34
Step-by-step explanation:
Total Cost = Fixed Charge + 0.50 * number of text messages
Total Cost = 52 dollars.
text Messages = x
Fixed charge = 35 dollars.
Equation
Total Cost = Fixed Charge + number of text message * 0.50
Solution
52 = 35 + 0.50 * x Subtract 35 from both sides
52 - 35 = 35-35 + 0.50x Combine
17 = 0.50x Divide by 0.50
17/0,50 = 0.50*x/0.50
x = 34 text messages
