question 74

Multiple Choice

Solve. Assume the exercise describes a linear relationship.
-When making a telephone call using a calling card, a call lasting 4 minutes costs $\$ 1.30$ . A call lasting 14 minutes costs $\$ 3.30$ . Let $y$ be the cost of making a call lasting $x$ minutes using a calling card. Write a linear equation that models the cost of making a call lasting $\times$ minutes.

• A) \(y = 0.2 x - 10.7\)
• B) \(y = 5 x - \frac { 187 } { 10 }\)
• C) \(y = - 0.2 x + 2.1\)
• D) \(y = 0.2 x + 0.5\)
