Answer:
first evening, 10 calls, second evening 80 calls, third evening, 20 calls.
Step-by-step explanation:
if the number of calls received during the first evening is X, then the number of calls received during the third evening is X+10 as the third evening received 10 more calls than first evening. The second evening received 4 times of third so 4X+10. Add them up together and put them equal to 110.
X+10+X+4X+40=110
6X+50=110
6X=110-50
6X=60
X=10
First evening, 10 calls,
second evening 80 calls; 4X+40, 4(10)+40=80
third evening 20 calls; X+10, (10)+10=20
Answer:
0.5 I think. because for every 2 on the x axis, it grows 1 on the y axis.
divide 187.50 by 12.5 to find hourly rate
187.50/12.50 = 15 dollars per hour
now divide 465 by 15 for number of hours
465/15 = 31 hours
double check by multiplying 31 by 15 ( 31 x 15 = 465)
