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
Step-by-step explanation:
On solving denominator →
(16x⁴)^¼ = [(2x)⁴]^¼ = 2x ....eq.1 { 16x⁴ = (2x)⁴ }
Numerator = 2x²
fraction = 2x² / 2x { from eq.1 }
Simplest form = x
