Step-by-step explanation:

Let the cost of the mooncake with two egg yokes be $ “x” and that of the mooncake with 1 egg yolk be $ “y”.

It is given that the mooncake with two egg yolks costs $2 more than the mooncake with one egg yolk, therefore the eq. is,

x = 2 + y

⇒ x – y = 2 ……. (i)

Also given, the cost of 6 mooncakes with two egg yolks and 5 mooncakes with one egg yolk is $ 130.8, therefore the eq. is,

6x + 5y = 130.8 ……. (ii)

Now,

Multiplying by 6 throughout the eq. (i) and then subtracting from eq. (ii), we get

∴ y = 118.8/11 = 10.8

Substituting y = 10.8 in eq. (i), we get

x – y = 2

⇒ x = 2 + 10.8 = $12.8

Thus, the cost of a mooncake with two egg yolks is $12.8.
