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

$77(x+5y = 35)\\x+35y=245\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(7x+35y)-(7x+3y)=245-53\\7x+35y-7x-3y=192\\32y=192$

Dividing both sides by 32

$\frac{32y}{32}=\frac{192}{32}\\y=6\\$

Putting y=6 in Eqn 2

$x+5(6)=35\\x+30=35\\x=35-30\\x=5$

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