Answer:
-7/3 is c
-2.9 is a
-2 5/8 is b
Step-by-step explanation:
-5/2 = -2.5
-7/3 > -2.5, so -7/3 is c
-6/2 = -3
-2.9 is very close to -3, so -2.9 is a
-2 5/8 is just a little less that -2.5, so -2 5/8 is b
21Step-by-step explanation:
Answer:
18 hours
Step-by-step explanation:
First, he worked 3 hours babysitting, so he already made 8*3=24 dollars.
This means he must work 200-24=176 dollars lifeguarding.
Divide that by how much he makes per hour, and 176/15=11.7333 hours lifeguarding.
Round that up if he can't do a fraction of an hour to get 12 hours lifeguarding.
This is possible because the total hours worked is 12+3=15, which is less than 18.
