Answer 1

Answer: The cost of appetizer is $8 and the cost of dessert is $6.

Explanation:

Let cost of appetizer be 'x'.

Let cost of desserts be 'y'.

According to question,

On Tuesday, it becomes,

`42x+19y=$450`

On Friday, it becomes,

`27x+36y=\$432`

By graphing method, we get that,

x= 8 and y = 6

Hence, the cost of appetizer is $8 and the cost of dessert is $6.

Answer 2

Appetizer cost = $8/-

Dessert cost = $6/-

Explanation:

Given that,

42x + 19 y= 450

27x +36 y = 432

Solving above equations, we get:

x= 8

y= 6

Therefore,

Appetizer cost = $8/-

Dessert cost = $6/-
