Answer:
The total cost of boring the 750 meters is $37,700.
Step-by-step explanation:
We know that the cost of the first meter is $250.
You want to keep on adding $50 each time you add a meter for example the cost of the second meter would be $300 because you add $250+50. Another way is that you can multiply so for the third meter it would be $350 as you $250+50(2).
In that way you can see a pattern forming and we want to subtract 1 variable when multiplying as you are already originally adding $50.
So now we want to form an equation to solve for the cost of 750 meters. The equation I would make is
250+50(750-1)
then you can solve to get 37700 that is shown below
250+50(750-1)
250+50(749)
250+37450
37700
That will be our answer!
The total cost of boring the 750 meters is $37,700.
