Answer:
60 packets
Step-by-step explanation:
Given that :
Unit cost of 20 packets
$5.49 / 20 =$0.2745
Unit cost of 60 packets :
$10.97 / 60 = $0.1828333
Unit cost of 90 packets :
$18.95 / 90 = $0.2105555
The 60 packets has the least cost per unit, hence it is the best buy.
The number would be 18.
Half of 18 = 9
Two thirds of 18 = 12
9 + 12 = 21
So 8x5=40 and 10×4=40 so you and your friend meet at the 40 th min
I know 17. The formula for INTERIOR angles is 180(n-2) divided by n. therefore 180(6-2) / 6 = 180 x 4 / 6 = 720 / 6 = 120.
and EXTERIOR angles is 360 divided by n, therefore 360/6 = 60.
