The employees at world soccer shop earn $8.50 per hour for the first 40 hours per week and $12.50 rate for any hours worked over 40. How much does an employee who works 52 1/2 hours in one week earn?

496.25 dollars

Step-by-step explanation:

Given that an employees earn $8.50 per hour for the first 40 hours per week 

and $12.50 rate for any hours worked over 40

If an employee works 52 1/2 hours

Let take away 40 hours from 52 1/2

That is 52 1/2 - 40 = 12 1/2 hours

The amount earn for 40 hours will be

40 × 8.5 = $340

The amount earn for the remaining hours will be

25/2 × 12.5 = $156.25

The total amount an employee earn to works for 52 1/2 hours will be

340 + 156.25 = $496.25

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
