Answer:
9:15 am
Step-by-step explanation:
Alarms sound at 7:15 am
Alarm frequencies are 40 min and 60 min
Since 40= 20*2 and 60= 20*3, the overlapping frequency is:
So next time both alarms sound at 7:15 am + 2 hours = 9:15 am
2/7 .2857
$3.98(estimated)
3c (cake) + 2(2c - 11) (bread) = 5.87
3c + 4c - 22 = 5.87
7c - 22 = 5.87
7c = 5.87 + 22
7c = 27.87
c = 3.98
