A) 27x ≤ 108
B) x ≤ 4
Explanation
Let x be the number of times you can fill up. It takes $27 each time, so this gives us 27x. We are budgeting no more than $108 on gas, so this means our inequality will be "less than or equal to":
27x ≤ 108
To solve this, we divide both sides by 27:
27x/27 ≤ 108/27
x ≤ 4
