Question:
A taxicab charges $2.00 for a ride, plus $0.40 for each mile, m, driven. The cab driven hopes to make a minimum of $5.00 from his next customer. Write and equation that could be used to solve for the value of m? Solution:
The cab driver wants to make a minimum of $5 on his next fare. this means that he will make an amount equal to or greater than $5. So the correct inequality should contain>=5. the cost of the cab ride is the sum of the fixed and variable costs. the fixed costs is $2. The variable cost is $0.40 for each of m miles driven. This makes the variable cos .40m. So the total inequality is 2 + 0.40m >= 5. Directions: Write the algebraic equation for the following word problems.
