Answer 1

Anwser-.

Lydia must sale 26 shoes in next 6 hours in order to meet her average sales rate.

Solution-

Lydia works at a shoe store where she averages 10 sales every 2.5 hours.

But, unfortunately she only sold 6 shoes in the first 2 hours.

But, she should have sold,
`(10)/(2.5)* 2=8` shoes in 2 hours

The amount of shoes she is behind her average = 8-6 = 2 shoes

The amount of shoes she usually sells in 6 hours is
`(10)/(2.5)* 6=24`

In order to cover up the amount in 6 hours she must sell the amount of shoes she usually sell in 6 hours + the amount of shoes she is already behind her average = 24 +2 = 26 shoes

Answer 2

In every 2.5 hours number of sales made by Lydia=10 sales

2.5 hours = 10 sales

Dividing both side by 2.5

In 1 hour = 4 sales

On a particular day

In 2 hours , number of sales made=6 sales

As we have to find number of sales in next 6 hours.

Total number of hours =2+6=8 hours

So, number of sales should be=8×4=32

But in 2 hours , she made 6 sales.

In order to meet his average sale , she should sell →32- 6=26 sales in next 6 hours.
