Dena is trying to solve this problem:
A store has a sale where every item has a sale price that is 20% less than the regular price. Write an expression that represents the sale price of an item if the
regular price is p dollars.
Dena said, "To find 20% of a number, I should multiply by 0.20. So the sale price of an item will be 0.20p."
Which statement best describes Dena's reasoning?
A Dena is correct.
Dena needs to subtract 0.20p from the regular price, p.
Dena should calculate the sale price as 20p and then divide by 100.
Dena is trying to solve an impossible problem because it doesn't say what the regular price is.

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.
