Hint:

This looks mean because of the decimals numbers, but calculate the total first.

Then work out how you can share your data over a 360° pie chart.

Answer:

75.13 + 62.95 + 41.92 = 180

so we have £180 to represent on a 360° pie chart.

360 ÷ 180 = 2

So £1 = 2°

G & E : 75.13 x 2 = 150.26 > 150°

Food : 62.95 x 2 = 125.9 > 126°

A M : 41.92 x 2 = 83.84 > 84°
