Answer:
Price after discount = 2.4 (1-.3)
Price after discount = 2.4 (.7)
Step-by-step explanation:
We know the cost after the discount.
Price after discount = original price - original price * discount rate
Factoring out the original price
Price after discount = original price (1- discount rate)
We know the discount rate = .3 and the original price is 2.4
Price after discount = 2.4 (1-.3)
Price after discount = 2.4 (.7)
Price after discount = 1.68
X^2 + 9 + 7 = 20
X^2 +16 = 20
X^2 = 20-16
X^2 = 4
Root 4 = 2
X=2
Let the temperature at 10am be x, then
x + 8 = 56
x = 56 - 8 = 48 degrees F
Let y be the temperature at 8am, then
y - 2 = 48
y = 48 + 2 = 50 degrees.
