.28 or 28% chance the randomly selected student is a senior. There are 50 total students in the band, and 14 seniors, so the probability that a senior is randomly selected is 14/50 or .28
Hey there!
Make the 2% to a decimal which is .02 and multiply it by 57 to find the sales tax
.02*57= 11.4
So 11.4 is the sales tax
So add 11.4 to 57 and you get
$68.40 is the total cost
Hope this helps!
Just multiply them together 0.67 x 0.3 = 0.201
