Question

Jerry needs to buy a used car, but only has $630.00. He wants to purchase a yellow sports car with 61,000 miles. The owner is asking $1,920.00. If he earns $120.00 per week at the Coffee Shack, which equation represents the number of weeks he is going to have to work until he can purchase the car?
 A. 
120x = 1,920
  B. 
120x + 630 = 1,920
  C. 
120x + 630 + 1,920 = 61,000(My answer)
  D. 
1,920 + 630 = 120x

No! The number of miles has nothing to do with this calculation. n = (1920 - 630) / 120 is 120 n = 1920 - 630 which is 120 n + 630 = 1920

the mileage is spurious information ... intended to mislead Jerry is going to work for x weeks at 120 per week ... then add that money to the $630 he already has to make up the selling price
