Question

A traveling salesman figures it costs 32 cents for every mile he drives his car. How much does it cost him (in dollars) a week to drive his car if he travels 420 miles a week?

A. $32.00
B. $420.00
C. $1,344.00
D. None

Answer 1

The weekly cost of driving 420 miles at 32 cents per mile is $134.40, which does not match any of the given answer choices, so the correct answer is D. None.

Step-by-step explanation:

A traveling salesman calculates that it costs 32 cents for every mile he drives his car. To determine the weekly cost of driving 420 miles, you need to multiply the cost per mile by the total number of miles driven.

Here's the calculation:

• Cost per mile: $0.32
• Weekly miles: 420
• Total weekly cost: 420 miles * $0.32/mile = $134.40

Therefore, the correct answer is D. None, because none of the options matches the calculated total weekly cost of $134.40.
