Holistic Question 1 Skye has just purchased a new house and decides to have her garden designed as demonstrated in the diagram. She has sourced two companies to lay the grass. She is provided with the following prices:
The premium hardwood timber decking she wants costs £35 per square metre. The labour cost to fit the decking is £350. She has managed to get the pond priced and fitted for £300.
Skye has set herself a budget of £1600. However, she has her heart set on astrograss. She is willing to go 20% over budget if she can get the astrograss. Can she afford to get everything including the astrograss? If so, which company should she go with? If not, what is her best option?

Holistic Question 2
The senior hospitality class are making shortbread to sell at the interval of the school show.
The recipe they are given is a ratio as shown below:
Butter : Sugar : Plain Flour
60g : 30g : 90g This is enough to make 6 large biscuits. The ingredients are purchased from the local supermarket Waitco:
Plain Flour: 500g = 40p 1.5kg = 75p Butter: 250g = £1.18 Caster Sugar: 500g = £1.10 2kg = £2.68 The class are optimistic and think they can sell 240 biscuits at 25p each. If they achieve their goal what is the maximum profit that the class will make?
