The square root of a perfect square will always be a whole positive or negative number.
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
So this is how you do it enjoy
we conclude that the store where you can get more sausages is in Peter the Butcher.
<h3>
Which shop is the best option?</h3>
You have £10.
Peter the Butcher sells 6 sausages for £2.30
The number of packages that you can buy is:
£10/£2.30 = 4.3
Rounding down to the next whole number, we conclude that here you can buy 4 packages, then:
4*6 = 24 sausages
4*£2.30 = £9.20
So here you can buy 24 sausages for £9.20
In Paul the butcher, you can buy 10 sausages for £3.50
Notice that here you can only buy 2 packages (because the cost of 3 packs would be £10.50, which is more than the amount you can spend).
Then here you only can get 20 sausages.
Then, we conclude that the store where you can get more sausages is in Peter the Butcher.
