shopkeeper sells tins of the same dog food in packs of four or packs of six.
Packs of four tins cost £1. Packs of six tins cost £1.20
Which is the best value for money?
You must show your working.
Answer:
Pack of 6
Step-by-step explanation:
Pack of 4 = £1
Packs of 6 = £1.20
Price per unit of each pack:
Pack of 4 ;
Unit price : cost / units
Unit price = £1 / 4 = £0.25
Pack of 6 ;
Unit price : cost / units
Unit price = £1.20 / 6 = £0.20
Pack of 6 is the best value for money as it has a lower unit price

Estimate the total weight of two million pounds worth of two pence coins in kilograms. A two pence coin weighs 7.1g.
Answer: 710,000 kg
Step-by-step explanation:
There are 100 pence in one pound.
The number of two pence coins in 1 pound is therefore:
= 100 / 2
= 50 coins
In 2 million pounds therefore, there will be:
= 50 * 2,000,000
= 100,000,000 two pence coins
If one coin weighs 7.1g, weight is:
= 100,000,000 * 7.1
= 710,000,000 g
A kg is 1,000 grams so the weight in kg is:
= 710,000,000/1,000
= 710,000 kg

What is the greatest surface area of a rectangular solid that can be built from 16 identical unit cubes?
Answer and explanation:
The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.
We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes
Surface area is therefore 16×6a²
Solve the following equation for x.
11x– 1 = -89
Answer:
x = -8
Step-by-step explanation:
11x– 1 = -89
Add 1 to each side
11x– 1+1 = -89+1
11x = -88
Divide each side by 11
11x/11 = -88/11
x = -8

At the zoo, Peter saw 9 animals. Some are kangaroos and some are
elephants. There are 30 legs in all. How many of each animal are there?
Answer:
6 elephants and 3 kangaroos in the zoo.
Step-by-step explanation:
Number of animals = 9
Number of legs seen = 30
But an elephant has 4 legs, while a kangaroo has 2 legs.
Let the number of elephant be represented by E, and the number of kangaroo by K.
So that,
E + K = 9 .................. 1
4E + 2K = 30 ............. 2
Multiply equation 1 by 2 to have
2E + 2K = 18 ............ 3
Subtract equation 3 from 1
2E = 12
E = 6
Substitute the value of E in equation 1
E + K = 9
6 + K = 9
k = 3
Thus, there were 6 elephants and 3 kangaroos in the zoo.
