A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
Step-by-step explanation:
Let,
Cost of 1 dozen doughnuts = x
Cost of 1 dozen croissants = y
According to given statement;
7x+3y = 53 Eqn 1
x+5y = 35 Eqn 2
Multiplying Eqn 2 by 7

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 32

Putting y=6 in Eqn 2

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
