Oliver has a box of toy cars, but he is not sure how many he has. If he arranges the cars in groups of four, he has three left over. If he arranges them in groups of 3, he has two left over and there are three left over when he puts them in groups of five. Oliver definitely doesn’t have any more than 30 cars, so how many does he have?

Question

Will the first equation be written as x/4+3

hero · Answer

x = cars per group

y = total cars 
   = 30

  y = (4x + 3) + (3x + 2) + (5x + 3)
30 = (4x + 3) + (3x + 2) + (5x + 3)
