Beth is paid $225 per week plus a commission of $20 per sale. this week she wants to earn at least $650. if s represents the minimum number of sales that sara needs this week, which inequality represents all the possible values of s?
a) 20s + 225 ≥ 650
b) 20s + 225 ≤ 650
c) 225s + 20 ≥ 650
d) 225s + 20 ≤ 650

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.
