Answer

Let ‘u’ be the number of sets of large muffin bought and ‘p’ be the number of set of small muffins bought

They spent the same amount
9u = 12p => 18u = 24p

Small muffin is 156 more than large muffins
7p = 2u + 156 => 63p = 18u + 1404

Substitute 18u =24p into the above equation

63p = 24p + 1404
39p = 1404
p = 36

Kaiming spent 12p = $432 which is also the same amount Jim spent.
