To be a successful entrepreneur you need to be able to make a **profit** from your business idea. To follow is a **multi-step** money problem for you to solve. List all the calculations you need to work out the final answer.

Tip: 1 litre = 1000ml

If you would like a **challenge**, solve the original problem instead!

Yaameen buys 3 litres of cola

1 litre of cola is £1

3 litre of cola is£3

and sells 100 ml for 25 pence then at the end of the day she gets £ 2.50 from one litre.

100ml=25p

1000ml=10 glass

10×25p=

10×25=250p

£2.50

She made £2.50 for one liter

3×£2.50=£7.50

£7.50-£3=£4.50

Her profit is £4.50

Well explained Abubaker!

money paid = 3 bottles x £1 per bottle = £3.

Total amount of cola = 3 x 1L = 3L = 3000 ml

1 glass of cola = 100 ml

total number of glasses = 3000 ml /100 ml = 30

money earned = 25p x 30 glasses = 750p = £7.5

profit =money earned – money paid = £7.5 -£3 = £4.5

Challenge

**************

5 Cans cost = 48p x 5 = 240p = £2.4

3 Bottles cost = £1.59 x 3 = £4.77

Cola cost = £4.77 + £2.4 = £7.17

Cola in cans = 330 ml x 5 = 1650 ml

Cola in Bottles = 1.25 L x 3 = 3.57 L = 3750 ml

All the cola = 3750 ml + 1650 ml = 5400 ml

1 glass of cola = 100 ml

total number of glasses = 5400 ml /100 ml = 54

money earned = 25p x 54 glasses = 1350p = £13.50

profit =money earned – money paid = £13.50 -£7.17 = £6.33

Great work Archi!

How did you work out 25p x 54?

Also we write 240p as £2.40.

Yasmin buys 3 bottle of cola 3×1=£3

She sells the cola in glasses 100 ml = 25p

1 litre cola= 10 glasses cola because 10×100=1000ml

10×25=250p

250×3=750p = £7.50

£7.50 – £3=£4.50

She does profit £4.50

Well done Xaxier!

-Yasim buy 3 bottles of cola costing £1 each, so she spent £3 in total.

-She sells a cup of cola for 25p (100ml in cup and 1000ml in a litre) , 10 cups x 25p = £2.50 per bottle, 3 x £2.50 = £7.50.

– she makes £4.50 profit.

-The can cost 48p x 5 bought = £2.40

-The bottles cost £1.59 x 3 bought = £4.17 *

Add together = £ 7.17

-can 330ml x 5 = 1650ml

-bottles 1.25 x 3 = 3750ml

Add together = 5400ml

So 1000ml = £2.50 x 5 (5000ml) = £12.50

And 400ml at 25p x 4 = £1.00

So she spend £7.17

Sold £13.50

Profit = £6.33.

Qasim you have shown a brilliant understanding of the problem. ☺

I have put a star next to the calculation you need to fix.

Keep up the good work!

Sorry Ms Khan l should of put £4.77, rather than £4.17.

Thank you for fixing your mistake!

3×1 =3

What other steps do you need to do?

25 times 30=£7.50p

I don’t know what the next one is

Hi James,

Step 1 – How much Yasmin spends?

Step 2 – You have done this. (How much Yasmin makes?)

Step 3 – Profit made.

Bronze

Yasim buys three bottles of coco cola.

1 .3×1=£3.

She sells half a bottle which is 1000ml =25p.

Yasim buys 5 cans and 3 bottles .

2. Ten x onehundred=1000ml.

10×25=250

The profit makes four pound fifty.

Nearly there Mishaal.

She makes £2.50 from each bottle.

So your next step is £2.50 x 3.

Then your last step is to work out the profit.

25 times 30=£7.50p

£7.50-£=£4.50

Thank you for completing the task!

1litre x 3 =£3.

1litre= 1000m)

1000 times 3=3000ml

100ml Times 10=1000ml

100ml times 30=3000ml

A good start Abdulah, now work out how much profit Yasmin made.

Yasmin buys 3 bottle of cola 3×1=£3

She sells the cola in glasses 100 ml = 25p

1 litre cola= 10 glasses cola because 10×100=1000ml

10×25=250p

250×3=750p = £7.50

£7.50 – £3=£4.50

She does profit £4.50

Absi that is well explained! 🌟
