Which of the following functions represents a cell phone bill if there is a monthly charge of 20 dollars plus 6 cents for each m
inute of use? f(x) = 20 + 6x f(x) = 20.06x f(x) = 20 + 0.06x
2 answers:
It would be f(x) = 20 + 0.06x
Answer:
Option 3rd is correct

Step-by-step explanation:
Let x be the time in minutes and f(x) be the cell phone monthly bill.
Given the statement:
if there is a monthly charge of 20 dollars plus 6 cents for each minute of use

2y - 3/5 = 1/2
2y = 1/2 + 3/5
- Let's make the two fractions have common denominators.
- Multiply 1/2 by 5/5 and 3/5 by 2/2.
- 1/2 * 5/5 = 5/10
- 3/5 * 2/2 = 6/10
2y = 5/10 + 6/10
Add the two fractions.
2y = 11/10
Divide both sides by 2.
- 11/10 ÷ 2
- Use the Keep, Change, Flip method.
- Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
- 11/10 × 1/2 = 11/20
y = 11/20
