Mr. rosskamm went to the mall and bought 2 pairs of sneakers for $55 each. he had a coupon for 30% off the combined total of the 2 pairs if sneakers. he also had a coupon for socks: buy 2 pairs, get 1 pair 20% off. if he bought 3 pairs of socks for $30 each, how much money did he spend?

He paid $107 for the sneakers (55+55)*0.7 = 107.

He paid $30 for socks, so in total he paid $137

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
