Here are the ingredients to make 12 cupcakes.Mark is making cupcakes to sell at his school play.Mark wants to make 1 cupcake for each adult and 2 cupcakes for each child.There will be 152 adults and 80 children at the school play.Mark can get these ingredients from the school kitchen. 5 kg butter 5 kg caster sugar 90 eggs 5 kg flourMake a shopping list of any ingredients Mark still needs, showing the amount of each ingredient.
Solution
First, let's calculate how many cupcakes Mark needs to make in total.
He wants to make 1 cupcake for each adult and 2 cupcakes for each child.
So, for the adults: 152 adults * 1 cupcake/adult = 152 cupcakes And for the children: 80 children * 2 cupcakes/child = 160 cupcakes
In total, Mark needs to make: 152 cupcakes (for adults) + 160 cupcakes (for children) = 312 cupcakes
The given recipe is for 12 cupcakes. So, to find out how much of each ingredient Mark needs for 312 cupcakes, we need to multiply the amount of each ingredient in the recipe by 312/12.
Let's calculate:
Butter: (5 kg / 12 cupcakes) * 312 cupcakes = 130 kg Caster sugar: (5 kg / 12 cupcakes) * 312 cupcakes = 130 kg Eggs: (90 eggs / 12 cupcakes) * 312 cupcakes = 2340 eggs Flour: (5 kg / 12 cupcakes) * 312 cupcakes = 130 kg
Now, let's subtract the amount of each ingredient Mark already has in the school kitchen from the total amount he needs:
Butter: 130 kg - 5 kg = 125 kg Caster sugar: 130 kg - 5 kg = 125 kg Eggs: 2340 eggs - 90 eggs = 2250 eggs Flour: 130 kg - 5 kg = 125 kg
So, Mark's shopping list should be:
- 125 kg of butter
- 125 kg of caster sugar
- 2250 eggs
- 125 kg of flour
