Answer:
<em>We must drive 8,553 miles to pay off the extra cost of the diesel engine</em>
Explanation:
Let's use simple logic and put the numbers in it to solve this problem. Each gallon of diesel fuel gives us 32 miles and each gallon of gasoline gives us 23 miles. On the other side, each gallon of diesel costs $3.54. That means to get 32 miles we have to spend $3.54, thus each mile costs $3.54/32=$0.11 when using diesel.
Each gallon of gasoline costs $3.69, it means each mile costs $3.69/23=$0.16 when using gasoline. The difference
$0.16-$0.11=$0.05 are the savings per mile when using diesel instead of gasoline. Since the diesel engine is $427.65 more expensive than the gasoline engine, we must drive $427,65/0.05=8,553 miles to pay off the extra cost of the diesel engine.
