Answer:

2 50ml bottles

Step-by-step explanation:

Reading through the question, we have:

For 80mL

C_1 = \pounds 55

For 2 50mL bottles.

The cost is calculated by the original cost + half the original cost.

i.e.

C_2 = \pounds 45 + \frac{1}{2} * \pounds 45

C_2 = \pounds 45 + \pounds 22.5

C_2 = \pounds 67.5

Next, is to calculate the unit price of each.

For 80mL

C_1 = \pounds 55

Unit\ price = 55/80

Unit\ price = 0.6875

For 2 50mL bottles.

C_2 = \pounds 67.5

Unit\ price - 67.5/(2 * 50)

Unit\ price = 67.5/100

Unit\ price = 0.675

By comparison, the 2 50mL is the best buy because it has smaller unit price

PLEASE HELP NEED THIS ONE TO PASS
Ghella [55]

Answer:

x  = 4.

Step-by-step explanation:

We see that it passes through the x axis at  the point (4, 0) so x = 4 is a solution.

Check by solving the equation

x^2 - 4x + 13 = 13

Subtract 13 from both sides:

x^2 - 4x = 0

x(x - 4) = 0

x = 0 or x - 4 = 0,  so:

x = 0 or  4.
