Answer:
Jacky can purchase 7 whole gallons of gas.
Explanation:
Let's set up an equation to solve this problem.
First, we know that 1 gallon of gas = $3.52
If Jacky has $27.56, then we can simple divide 27.56 by 3.52
= 7.8295454...
Since, the problem only asks for how many whole gallons of gas Jacky can buy, then we would only need to take the whole number of this answer (which is 7).
So, Jacky can only buy 7 whole gallons of gas.
