Liz goes on holiday to South Africa Liz wants to change £850 into south african rand
she wants to get as many 200 rand notes as possible

The exchange rate is £1=18.53 rand

Work out the greatest number of 200 rand notes that liz can get for £850

82 notes

Step-by-step explanation:

The computation is shown below:

Given that

£1= 18.53 rand

and since Linz has £850 so he would get the equivalent of

= $890 ×  18.53

= 16,491.7 rands

Now he wants the 200 rand notes so we considered it as the  highest note

So, the greatest no of 200 notes would be

= 16,491.7 ÷ 200

= 82.45

= 82 notes

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
