Answer 1

After 12 meals

Explanation:

A holiday meal costs a person $12.50 plus delivery fee of $30.

The same meal costs a person $15.00 with no delivery fee at good eats.

Let the number of meals be x

we cater charges = 12.50x + 30

Good eats charges = $15.00x

we cater become the better deal :

12.50x + 30 < 15.00x

30 < 15.00x - 12.50x

30 < 2.50x

x <
`(30)/(2.50)`

x < 12

After 12 meals we cater become the better deal.
