Answer: x/3
Step-by-step explanation:
There is no enough sufficient information in the question to determine the total cost to make the truck functional but we solve this type of question by assuming the total cost of the chosen truck to b "x". This means the cost price of the desired truck is x.
Let the amount you have saved be "y".
Since a local business has decided to support your business with 3times the amount you have saved and this money must be enough to buy the desired truck, then we equates the tripled amount you have to the cost price of the truck. That is:
3y = x
y = x/3.
This means that the minimum amount you must save to buy the truck must NOT be less than "x/3" where "x" is the total cost of functionality of the truck.
