Answer:
The total number of albums sold on the first day=34
Step-by-step explanation:
Derive expressions for the number of albums sold
each day;
Let;
the total number of albums sold on the first day=x
the total number of albums sold on the second day=y
but,
total number of albums sold on the second day is twice the total number of albums sold on the first day, therefor=, y=2×x= 2 x
The total number of albums sold for the two days can be expressed as;
Total sales=number sold on the first day+number sold on second day
where;
Total sales=102
number sold on the first day=x
number sold on second day= 2 x
replacing;
(x+2 x)=102
3 x=102
x=102/3
x=34
The total number of albums sold on the first day=34
Answer:
4/20 or 1/5 if you want it simplified
Answer:
134.38
This value represents 134.38
Step-by-step explanation:
Find the mean.
950+620+545+810+775+1120+905+775=6500
6500/8=812.5
Subtract the mean of numbers.
950-812.5=137.5
812.5-620=192.5
812.5-545=267.5
812.5-810=2.5
812.5-775=37.5
1120-812.5=307.5
905-812.5=92.5
812.5-775=37.5
Find the mean.
137.5+192.5+267.5+2.5+37.5+307.5+92.5+37.5=1075
1075/8≈134.38
This means that 134.38 is $134.38
