Answer:
C
Step-by-step explanation:
Let's say that the price of each normal cookie is n.
The equation would then be 7(n - .75)=2.80.
Use distributive property, getting 7n - 5.25=2.80.
Add 5.25 to each side of the equation, getting 7n=8.05.
Divide 7 from both sides of the equation, getting n=1.15.
5 times 3 is 15! i’m confused at the rest of the question!
(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
