Question

I need help with my khan, plz help meeee (7th-grade math)

Answer 1

Answer:

The equation is ⇒ 7( x - 0.75 ) = 2.8

The normal price of one cookie = $1.15

Step-by-step explanation:

Let the normal price is x

So, the cost of cookie today is x - 0.75

The price of 7 of them will be $2.8

So the equation will be:

7( x - 0.75 ) = 2.8

Solve for x:

x - 0.75 = 2.8/7 = 0.4

x = 0.4 + 0.75 = 1.15
