the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent? he spent 6p dollars on gasoline. he spent n + p dollars in all. he bought 15 gallons of gasoline. he bought 6 dollars worth of snacks.

Answer

Explanation:

Step1: Analyze the expression

The expression for the total amount spent is $15n + 2(3p)=15n + 6p$. Here, $15n$ represents the amount spent on gasoline (since $n$ is the price per - gallon of gasoline) and $6p$ represents the amount spent on snacks (since $p$ is the cost of each snack and $2\times3p = 6p$).

Step2: Evaluate each option

  • Option 1: The amount spent on gasoline is $15n$, not $6p$. So this option is false.
  • Option 2: The total amount spent is $15n + 6p$, not $n + p$. So this option is false.
  • Option 3: Since the amount spent on gasoline is $15n$ and $n$ is the price per - gallon of gasoline, the number of gallons of gasoline bought is 15. This option is true.
  • Option 4: The amount spent on snacks is $6p$, not 6 dollars. So this option is false.

Answer:

He bought 15 gallons of gasoline.
