14. The circle graph shows the results of an employment survey of 800
MariettaO [177]

Answer:

480 people were unemployed full time

Step-by-step explanation:

Looking at the graph, this is equal to 60%

This means that 60% of the total 800 are unemployed full time

Mathematically, that would be 60/100 * 800 = 480 people
