Question

for a party. 10 friends are buying 100 cups,100 plates a punchbowl, and 200 ballons.if the friends share the cost equally ,how much should each friend contribute

Answer 1

Answer:

Every friend would contribute 10% of total cost.

Step-by-step explanation:

As total shopping of 10 friends contains:

• 100 cups
• 100 plates
• One Punchbowl
• 200 balloons

As you have not specified the typical prices of buying things, so I am assuming that each part of every entity costs 1 unit. For example, one cup costs 1 unit, one plate costs 1 unit, one punchbowl costs 1 unit, and 1 balloon costs 1 unit.

Note: Just assume, that 1 unit could be any currency, like 1 unit means one US dollar etc.

It means,

• 100 cups costs 100 units
• 100 plates cost 100 units
• A punchbowl costs 1 unit
• 200 balloons cost 200 units

So, total cost of 100 cups, 100 plates, one Punchbowl, and 200 balloons:

100 + 100 + 1 + 200 = 401 units

As

Total cost of all shopping = 401 units

Total friends = 10

As the friends share the cost equally. Hence, just divide the total cost by total number of friends to establish the contribution of each friend.

Contribution of each friend = Total cost all shopping / Total friends

Contribution of each friend = 401/10 ⇒ 40.1 units

So, each friend would contribute the cost of 40.1 units.

In other words, every friend would contribute 10% as 10% of 401 = 40.1 units.
