Responder:
Número de bueyes = 12
Número de vacas = 24
Explicación paso a paso:
Dado que :
Número de vacas compradas = 2 veces el número de bueyes;
Sea número de bueyes = y
Número de vacas = 2 años
Costo de la vaca = 70
Costo de bueyes = 85
Costo total = 2700
Por lo tanto;
(2 años * 70) + (y * 85) = 2700
140 años + 85 años = 2700
225 años = 2700
225 años / 225 = 2700/225
y = 12
Número de bueyes = y = 12
Número de vacas = 2y = 2 * 12 = 24

Answer: She paid the most for the gas in the first stop ($3.35 per gallon).
Step-by-step explanation:
1. At the first stop she put in 7.1 gallons of gas and paid $23.79, so she paid:
$23.79/7.1 gallons=$3.35 per gallon.
2. At her second stop she put in 5.8 gallons of gas and paid $19.08, then the price per gallon was:
$19.08/5.8 gallons= $3.28 per gallon.
3. At the third stop she put 6.6 gallons and paid $20.39, then:
$20.39/6.6 gallons=$3.08 per gallon.
4. Then, you can conclude she paid the most for the gas in the first stop ($3.35 per gallon).
