Answer:
Formula: [tex]c=\frac{sale\ price\ of\ 7}{7}+\$0.75[/tex]
Normal Price: [tex]\$1.15[/tex]
Step-by-step explanation:
First, you have to find the current price of one cookie.
Since 7 cookies cost $2.80, then the price for one sale price cookie would cost
Then you would have to add the $0.75 to the sale price to get the normal price.
[tex]\$0.4\ +\ \$0.75=\$1.15[/tex]
The normal price of a cookie would be $1.15.
The formula to get that answer would be:
[tex]c=\frac{sale\ price\ of\ 7}{7}+\$0.75[/tex]
Hope this helps!
