that's a lot of numbers

Answer:

1). 8.556 pizzas

2).£1.5625

Step-by-step explanation:

1). dimensions of the tray is 640mm by 420mm which is = 64cm by 42 cm

The area if the tray = L*B

Area = 64*42

Area = 2688cm²

Pizza has a diameter of 20cm

Radius = 10cm

Area of the pizza =πr²

Area= 3.1416*10²

Area= 3.1416*100

Area = 314.16cm²

Number of pizza it will contain is

Area of tray/area of pizza

= 2688/314.16

=8.556 pizzas

2). 96 slice of pizza cost £114

1 slice = 114/96=£ 1.1875

But then 96*x = £150

X = 150/96= £1.5625
