500A survey was taken of students at the university concerning their

enrollment in art courses. Each of 400 students were asked to answer yes or no to each of the following questions:

Are you enrolled in a painting course?Are you enrolled in a drawing course?

Are you enrolled in a clay course?So far the following data from the survey has been tabulated:

210 of the students are enrolled in a drawing course110 are enrolled in both a painting and a clay

160 are enrolled in a drawing but not a painting60 are enrolled only in a clay course

20 are enrolled in all three course areas230 are enrolled in a clay course

180 are enrolled in only one of the three areas

The dean of art is interested to know the answers to the questions:How many students are enrolled in none of these three areas?

How many students are enrolled in at least one of the three areas?How many of the students are enrolled in at least two of the three areas?

How many of the students are enrolled in a painting course?

300You are using solid colored fabric that costs $.06 per square and patterned

fabric that costs $.10 per square to make a quilt. You need 660 squares to

complete the quilt. Write an equation that gives the total cost c as a function of the number n of solid squares used. Then find the total cost if you use 200 solid

colored squares.
