Minh is buying tulip bulbs that cost $0.75 each. He has $20 to spend. Which rule can use to find the amount of change he will receive if buys n tulips bulbs?
F f(n) = 0.75n
G f(n) = 0.75n
H f(n) = 20 - 0.75n
J f(n) = 20n/0.75
H f(n) = 20 - 0.75n

Eli has 8 equally sized slips of paper. He writes a number on each, so that the slips of paper are labeled 1 through 8. He places all 8 slips in a hat.
a. What is the sample space when randomly choosing a slo of paper from the hat?
b. What is the probability of drawing a number greater than 6?
c. Eli is trying to draw a number greater than 6. He draws 4 and puts it back into the hat. He then draws a 2 and puts it back in the hat. What is the probability that he draws a number greater than 6 on his next try? Why?
d.Is there a greater chance of drawing an even number or drawing a number less than 4? Justify your answer.
a. P( slip out of hat) = 1/8
b. P( greater than 6) = 1/4
c. P( greater than 6) = 1/4
d.A greater chance of drawing an even number because there are 4 even number but only 3 numbers less than 4.
