To determine how much you still owe, I need to know the total cost of the gas. Could you please provide that amount?

total cost of the gas
40.1

If the total cost of the gas is $40.10, and your friend gave you $31.56, you can calculate what you still owe by subtracting the amount your friend gave you from the total cost:

\[ \text{Amount Owed} = \text{Total Cost} - \text{Amount Given} \] \[ \text{Amount Owed} = 40.10 - 31.56 = 8.54 \]

So, you still owe $8.54.

According to your car's navigation system, you need to drive 448.6 miles to reach your destination. You have volunteered to drive the first 1/4
of the trip. How many miles will you be driving?(2 points)

112.15 miles

110 miles

To find out how many miles you'll be driving for the first 1/4 of the trip, you can multiply the total distance by 1/4:

\[ \text{Miles Driven} = \text{Total Distance} \times \frac{1}{4} \] \[ \text{Miles Driven} = 448.6 \times \frac{1}{4} \] \[ \text{Miles Driven} = 448.6 \div 4 = 112.15 \]

So, you'll be driving 112.15 miles.

The correct response from your provided options is 112.15 miles.

You and two other friends took turns driving during the trip. You each drove for the following amounts of time: 5/6
of an hour, 2 1/8
hours, and 3 1/2
hours. How long did you all spend driving?(2 points)

To determine the total time spent driving by you and your two friends, we will first convert each time into an improper fraction or a decimal, then add them together.

  1. Convert each driving time:

    • \(5/6\) of an hour is already a fraction.

    • \(2 \frac{1}{8}\) hours can be converted to an improper fraction: \[ 2 \frac{1}{8} = \frac{16}{8} + \frac{1}{8} = \frac{17}{8} \]

    • \(3 \frac{1}{2}\) hours can also be converted to an improper fraction: \[ 3 \frac{1}{2} = \frac{6}{2} + \frac{1}{2} = \frac{7}{2} \]

  2. Add the times together: \[ \text{Total time} = \frac{5}{6} + \frac{17}{8} + \frac{7}{2} \]

    To add these fractions, we need a common denominator. The least common multiple of 6, 8, and 2 is 24.

    • Convert each fraction: \[ \frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24} \] \[ \frac{17}{8} = \frac{17 \times 3}{8 \times 3} = \frac{51}{24} \] \[ \frac{7}{2} = \frac{7 \times 12}{2 \times 12} = \frac{84}{24} \]
  3. Now sum these fractions: \[ Total = \frac{20}{24} + \frac{51}{24} + \frac{84}{24} = \frac{20 + 51 + 84}{24} = \frac{155}{24} \]

  4. Convert \(\frac{155}{24}\) to a mixed number: \[ 155 \div 24 = 6 \quad \text{(whole number)} \] The remainder is: \[ 155 - (24 \times 6) = 155 - 144 = 11 \] So, \(\frac{155}{24}\) can be expressed as: \[ 6 \frac{11}{24} \]

Thus, the total time spent driving is 6 11/24 hours.

The correct response is 6 11/24.

After driving for a couple of hours, you and your friends decide to stop at a gas station for some snacks. Four sodas cost you a total of $4.67. What is the total cost for one soda?(2 points)

$0.67

To find the cost of one soda, you can divide the total cost of the sodas by the number of sodas purchased.

Given that four sodas cost a total of $4.67:

\[ \text{Cost of one soda} = \frac{\text{Total Cost}}{\text{Number of Sodas}} = \frac{4.67}{4} \]

Calculating this:

\[ \text{Cost of one soda} = 1.1675 \]

Rounding to two decimal places gives you $1.17.

So, the total cost for one soda is $1.17.

The correct response is $1.17.

A Snickers bar costs you 34

To find the total cost of your snack purchase, you need to add the cost of each item together:

  • Cost of a Snickers bar: $0.34
  • Cost of a bag of chips: $1.25
  • Cost of a hot dog: $2.23

Now, add these amounts together:

\[ \text{Total Cost} = 0.34 + 1.25 + 2.23 \]

Calculating this step-by-step:

  1. Add the first two items: \[ 0.34 + 1.25 = 1.59 \]

  2. Now add the cost of the hot dog: \[ 1.59 + 2.23 = 3.82 \]

So, the total cost of your snack purchase is $3.82.
