Answer:
Jacky can purchase 7 whole gallons of gas.
Step-by-step explanation:
Let's set up an equation to solve this problem.
First, we know that <em>1 gallon of gas = $3.52</em>
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.
Each person gets 1 1/4 bars.
You divide the 5 bars by 4 people: 5/4 = 1 1/4
You will need to use the compound growth formula - this is...
final number = starting number * (multiplier ^ number of years)
We can turn the 6% into a multiplier by dividing it by 100 and adding 1 on to it:
6/100 = 0.06
0.06+1 = 1.06
Then we can say that the starting number is 254 and the number of years is X, we can then place this all into the original formula:
Final population = 254 * (1.06 ^ X)
Hope this helps! :)
