Answer 1

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!

Answer 2

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.
