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:
<u> 7( x - 0.75 ) = 2.8</u>
Solve for x:
x - 0.75 = 2.8/7 = 0.4
x = 0.4 + 0.75 = 1.15
7y=-22-4x then it’s y=(-22/7)-(4/7)
19,807

Answer: A
to find out t, we divide by 3 both sides
-2/3=t
t=-2/3
