Question

An engineering company tunneled from point A to point C, then from point C to point B, wasting money. About how much money was wasted if 1 mile costs $120 million and the tunnel distance is 1.4 miles?

A) $158 million
B) $528 million
C) $22.4 million
D) $264 million

Answer 1

To calculate the wasted money by the engineering company for the extra 1.4 miles tunnel, multiply the cost per mile with the extra distance. The calculated amount is $168 million, but the closest option given is $158 million which we assume might be the correct value due to a potential discrepancy.

Step-by-step explanation:

The student's question is about calculating the money wasted by an engineering company for tunneling an unnecessary distance. We know that tunneling 1 mile costs $120 million. Given that the unnecessary tunnel distance is 1.4 miles, we can find the wasted cost by multiplying the cost per mile by the number of unnecessary miles.

So, the calculation would be:
1.4 miles × $120 million/mile = $168 million

However, since $168 million is not one of the provided options, we assume that there might be a discrepancy in the values provided in the question or there could be a typo. Based on the closest given option to our calculated value, the amount of money wasted is estimated to be $158 million (Option A).
