DOES ANYONE KNOW THE ANSWER TO THIS?? PLEASE HELP! 50 POINTS!!

I buy my sandwiches for each day from the work canteen. The prices are shown in the table
below.

Filling Small roll Large roll Baguette
Cheese $1.00 $1.20 $1.50
Egg $1.20 $1.50 $1.80
Beef $1.80 $2.00 $2.20
Chicken $1.80 $2.00 $2.50
Ham $2.00 $2.50 $2.80
Pork $2.20 $2.50 $2.80
For salad add 20¢ 30¢ 50¢

I plan to have a large cheese roll on Monday and Thursday, a chicken baguette with salad on
Tuesday and a large egg roll on Wednesday and Friday.
The canteen has a special offer: if I order all of my sandwiches for the week then I will get the
cheapest one free.
How much will I need to pay for my sandwiches for the week?
A $6.00
B $6.70
C $7.20
D $8.40
