Answer:

£531.52

Step-by-step explanation:

We are given the profit in week 1 and information about week 2. We are asked for the difference between week 2 profit and week 1 profit.

In week 2, pizza is sold 4 ways. The diagram shows the numbers of pizzas sold each way. The table shows the profit made for each way the pizza was sold. We need to add up the profits from each of the sales to find the profit for week 2.

10-inch/normal price: profit = 407×£3.72 = £1514.04
10-inch/offer price: profit = 358×(-£0.49) = -£175.42
12-inch/normal price: profit = 169×£5.26 = £888.94
12-inch/offer price: profit = 142×(-£0.04) = -£5.68

Then the total profit in week 2 is ...

£1514.04 -175.42 +888.94 -5.68 = £2221.88

So, profit in week 2 exceeds profit in week 1 by ...

£2221.88 -1690.36 = £531.52 . . . more profit in week 2

Given that the triangles shown below are similar, what is the value of x?

Montano1993 [528]

Using proportions, it is found that the value of x is of x = 5, hence option A is correct.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:

A side with a length of x is proportional to a side with length 25.

A side with a length of 3 is proportional to a side with length 15.

Hence:

$\frac{x}{25} = \frac{5}{25}$

Simplifying the denominators:

x = 5.
