Let’s check out your problem:

Toby rides his bike to school every day and to his best friend's house regularly. One week, he rode to and from school $5$ times and to and from his best friend's house $3$ times. He rode a total of $14.4$ miles that week. The next week, he rode to and from school $4$ times and to and from his best friend's house $6$ times. He rode a total of $14.4$ miles that week, too.$\newline$This system of equations can be used to represent the situation:$\newline$$$5x + 3y = 14.4$$$\newline$$$4x + 6y = 14.4$$$\newline$Which statement is correct?$\newline$Choices:$\newline$(A)In the system of equations, $x$ represents the total distance Toby traveled to and from school each week, and $y$ represents the total distance he traveled to and from his best friend's house each week.$\newline$(B)In the system of equations, $x$ represents the round-trip distance to and from Toby's best friend's house, and $y$ represents the round-trip distance to and from Toby's school.$\newline$(C)In the system of equations, $x$ represents the round-trip distance to and from Toby's school, and $y$ represents the round-trip distance to and from his best friend's house.$\newline$(D)In the system of equations, $x$ represents the total distance Toby traveled to and from his best friend's house each week, and $y$ represents the total distance he traveled to and from his school each week.$\newline$What was the total distance Toby traveled to and from school the first week?$\newline$____ miles$\newline$
