: You fill your car's gas tank when it is about 1/2 empty. The next week, you fill the tank a second time when it is about 3/4 empty. If you buy a total of 18 1/2 gallons of gas on these two days, about how many gallons does that tank hold? This question is from textbook Algebra 1
You can put this solution on YOUR website! You fill your car's gas tank when it is about 1/2 empty. The next week, you fill the tank a second time when it is about 3/4 empty. If you buy a total of 18 1/2 gallons of gas on these two days, about how many gallons does that tank hold?
----------------
Let x-gallons be the tank capacity.
1st Buy: (1/2)x gallons
2nd Buy: (3/4)x gallons
----------------
EQUATION:
(1/2)x + (3/4)x = 18 1/2
(5/4)x = 37/2 = 74/4
5x = 74
x = 14.8 gallons (tank capacity)
