At a theme park, the admission price for children is $7 and the admission price for adults is $21. The total amount the theme park collects in admissions for the day is $5439. The total number of visitors is 305. let c be the number of children and let y be the number of adults. which system represent the situation 21x+7y=5439
x+y=305

7x+21y=5439
x+y=305

x+y=5439
21x+7y=305

x+y=5439
7x+21y=305

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
