Answer:
Hence, the normal price of each cookie= $ 1.15.
Step-by-step explanation:
Cookies are on sale!
Today each cookie costs $0.75 less than the normal price.
So let c be the normal price of one cookie.
Hence, today 1 cookie will cost= $ (c-0.75)
Right now if you buy 7 of them it will only cost you $2.80!
Hence,
cost of 7 cookie= 7×(c-0.75)
This means that:
7×(c-0.75)=2.80
i.e. 7c-7×0.75=2.80
⇒ 7c-5.25=2.80
⇒ 7c=0.80+5.25
⇒ 7c=8.05
dividing both side by 7 we get:
c=1.15
Hence, the normal price of each cookie= $ 1.15.

hello,
Answer:
w = 21
x = 13
y = -11
z = -16
Step-by-step explanation:
Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...
Thus, w = 17 - (-4) = 17 + 4 = 21
x = 12 - (-1) = 12 + 1 = 13
y = -3 -8 = -11
z = -2 -14 = -16
These are the values of w, x, y and z , respectively.
