Answer:
$1.15
Step-by-step explanation:
Let the current price of the cookie be C whilst the normal price is c.
From the information we can deduce two equations.
Firstly, since they are $0.75 less than usual:
C+$0.75=c
Secondly, since seven cost $2.80
7C=$2.80
We can simplify this equation by dividng by 7
C=$0.40
Now combine the equations via substitution this value above into the first equation
$0.40 + $0.75= c
c= $1.15
Therefore the normal price is $1.15
