Step-by-step explanation:
Let the normal price of 1 cookie = 'x'.
Given that each cookie costs 0.75 less than normal price.
Today's each cookie cost = x - $0.75.
Given that if you buy 7 of them, it cost you $2.80.
So, the total price of 7 cookies:
⇒ 7(x - $0.75) = $2.80
⇒ x - $0.75 = $2.80/7
⇒ x - $0.75 = $0.4
⇒ x = $0.4 + $0.75
⇒ x = $1.15
Therefore:
The Equation is : 7(x - $0.75) = $280
Normal price o each cookie = $1.15
Hope it helps!
Step-by-step explanation:
This one is very easy to do.
Let the normal price be $x
According to the question,
Each cookie costs $0.75 less than the normal price.
=> x - $0.75
Also given that,
7 of them costs $2.80
So, Each of them costs $2.80/7 = $0.4
Hence, x-$0.75 = $0.4
========> x = $0.4+$0.75 = $1.15
Therefore, the equation is 7(x-0.75) = $2.80.
