i got it, thank you for giving the hint. It is d, since after subtracting 55, the only divisible by 6 that has a multiple of 5 is d.

There must be 10 costing $3 and 5 costing $5. That adds up to $55. The number of z's sold must be a multiple of 5 and the amount spent on z's must be a multiple of 6 x 5 = 30.
$145 (d) is a possibility if 15 z's are sold.
