Question

  1. a taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. the rule $c = 0.40m + 1.75$ describes the relationship between the number of miles $m$ and the total cost of the ride $c$. what is the charge for a 2.7 - mile ride?

$1.08
$5.13
$2.15
$2.83

Explanation:

Step1: Identificar la fórmula y el valor de m

La fórmula es \( c = 0.40m + 1.75 \), y para un viaje de 2.7 millas, \( m = 2.7 \).

Step2: Sustituir m en la fórmula

Sustituimos \( m = 2.7 \) en la fórmula: \( c = 0.40 \times 2.7 + 1.75 \).

Step3: Calcular el producto

Primero, calculamos \( 0.40 \times 2.7 \). \( 0.40 \times 2.7 = 1.08 \).

Step4: Sumar el costo fijo

Luego, sumamos el costo fijo de 1.75: \( c = 1.08 + 1.75 \).

Step5: Calcular el total

\( 1.08 + 1.75 = 2.83 \)? Espera, no, 1.08 + 1.75 es 2.83? Wait, no, 1.08 + 1.75: 1 + 1 = 2, 0.08 + 0.75 = 0.83, así que total 2.83? Wait, pero las opciones son $1.08, $5.13, $2.15, $2.83. Wait, 0.40*2.7=1.08, then 1.08 +1.75=2.83. Sí, así que:

Wait, volviendo: \( 0.40 \times 2.7 = 1.08 \), luego \( 1.08 + 1.75 = 2.83 \). Entonces el costo total es $2.83.

Answer:

$2.83
