A store sold 102 record albums during a two-day sale. Twice as many albums were sold the second day as the first How many albums were sold the frist day?

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
