At a shoe store, a salesman earns a weekly salary of $150. A salesperson is it also paid 2$ each pair of shoes he or she sells during the week.

150+2x

150 + 2(pairs) = ?

To calculate the total earnings of the salesperson in a week, you need to consider two components: the weekly salary and the additional earnings based on the number of shoes sold.

1. Calculate the weekly salary:
The salesman's weekly salary is given as $150.

2. Calculate the additional earnings from selling shoes:
For each pair of shoes sold, the salesperson earns $2.

To find the additional earnings, you need to know how many pairs of shoes were sold during the week. Once you have that information, you can multiply the number of pairs sold by $2 to calculate the additional earnings.

Let's assume the salesperson sold x pairs of shoes during the week.

Additional earnings = Number of pairs sold x $2
Additional earnings = x * $2 = $2x

3. Calculate the total earnings:
To find the total earnings, you need to add the weekly salary to the additional earnings from selling shoes.

Total earnings = Weekly salary + Additional earnings
Total earnings = $150 + $2x

Therefore, the total earnings for the salesperson in a week is $150 plus $2 multiplied by the number of pairs of shoes sold.
