think of the cents as percentages of the dollar. so ground maintenance takes up 55% of the dollar, etc. now, we want to divide a circle based on these percentages. so a slice of the pie with 55% of the degrees at the center will represent the ground maintenance and so on for the rest. how do we find the degrees? well, we remember that "percent" means "out of 100" and "of" means multiply and a circle has 360 degrees. so,
for ground maintenance, we have:
so the slice with corresponds to the ground maintenance. do similar calculations for the others, and then draw your pie chart. (oh, you just have to do "animal care" well, that's even better)
what would the answer be?
