Meal Deals
15
Meal Deals
A meal deal is where you combine a number of food and drink items for a set price.
Supermarkets often sell lunch meal deals
Fast food restaurants might sell meal deals
Take away restaurants usually have meal deals
Restaurants sometimes have meal deals or a 'set menu'
16
Meal Deals
It is usually cheaper to buy a meal deal than buy the items individually
We are going to look to see how much money we can save with a meal deal.

Meal Deals

Meal Deals

I will choose the Black Truffle Mac & Cheese (£10.95)
19
Meal Deals
For the dessert, I choose the Tiramisu (£6.50)
What would you choose?
20
Meal Deals
To drink, I choose San Pellegrino Limonata (£1.95)
What would you choose?
21
Meal Deals
So I chose the Mac & Cheese (£10.95)
I chose the Tiramisu (£6.50)
And I chose the Limonata (£1.95)
That adds up to (£19.40)
22
Meal Deals
If I bought the items individually, the meal would cost £19.40
The meal Deal costs £17.00
£19.40 - £17.00 = £2.40
If I bought the meal deal, I would save £2.40
