Approximately 85% of applicants get their G1 drvier's license the first time they try the test. 80
applicants are scheduled to take the next test.

One number is four more than a second number. Four times the first is 2 less than 6 times the
second. Find the numbers
4(x+4) = 6x 2
4x + 16 = 6x - 2
18 = 2x
x = 9, the second number. The first is 13.

17 kids with a 12 percent recidivism rate
19 kids with a 37 percent recidivism rate
22 kids with a 55 percent recidivism rate
What is the average recidivism rate for all these 58 kids?
Group1: number of recids/17 = 0.12 -> no recids = 2 in this group
