To find out when Miguel and Christina will have the same amount of gas in their tanks, we can set up an equation.
Let's say after x weeks, Miguel will have used 1.5x gallons of gas and Christina will have used 1x gallons of gas.
Since Miguel's car has a 20-gallon capacity, the amount of gas remaining in his tank after x weeks is 20 - 1.5x gallons.
Similarly, since Christina's car has a 16-gallon capacity, the amount of gas remaining in her tank after x weeks is 16 - 1x gallons.
To find out when they will have the same amount of gas in their tanks, we can set up an equation and solve for x:
20 - 1.5x = 16 - x
Simplifying the equation, we get:
4 = 0.5x
Divide both sides by 0.5:
8 = x
Therefore, they will have the same amount of gas in their tanks after 8 weeks.
So the correct answer is:
• After 8 weeks they will have the same amount of gas in their tanks.
has a 20-gallon capacity, and Christina's car has a 16-gallon capacity. Miguel uses 1.5 gallons of gas per week, and Christina uses 1 gallon of gas per week. When will Miguel and Christina have the same amount of gas in their tanks? (1 point)
• After 8 weeks they will have the same amount of gas in their tanks.
• After —8 weeks they will have the same amount of gas in their tanks.
• After 1.6 weeks they will have the same amount of gas in their tanks.
• After week they will have the same amount of gas in their tanks.
